Sound Quality Automatically Reduced On Import

[anonymous_user_e04fe733]

Yeah, also super annoyed by this. It needs to be fixed.

[Rama]

I Know The Solution Algorithm (Please see below)

The Issue as Summarized Very Nicely By UE’s Loving and Adoring Family Members:

@anonymous_user_1ec0f28b

More worrying is the loss of bottom end. You are right, under 200Hz it starts to fall away considerably. I haven’t been using UE4 audio for long enough to know if this has always been the case but it has been an issue for at least the last year. It’s a pretty serious problem as far as I’m concerned.

@SoundFX_Studio

Unfortunately, even in 48kHz format, you get a distorted file. The upper frequencies in 48kHz format are cut less than if you add a file in the 44.1kHz format. But then lower frequencies are beginning to be reduced. For mobile small projects, this is probably not essential. But for serious projects - this is unacceptable.

@esadreb

Hello, has anyone came up with solution to this? I am loosing everything bellow 200Hz both on 44,1 kHz and 48kHz, 16bit. Also around 5dB of gain which you can see from the pics below.

Hi everyone!

My 4.24 Experience

The issue seems pretty simple

When UE4 imports, a compression algorithm is automatically run at the default 40% setting, that’s why a large file takes any time to import at all.

If no compression was occurring, the file would import instantly.

A Wave32 bit file (which I am using for high quality bass myself) should not take any time at all to import.

No one has to check engine code to know this, just observe how long import takes (x seconds), then observe how long it takes to run any compression setting other than 40. It is the same x seconds of duration for any given file,

Which means the compression algorithm is running on import.

That by itself is not an issue, the issue is that when you change compression, the algorithm is re-run on the already compressed file, rather than the original uncompressed file, which means having 0 compression is unattainable, 40% is the max cap of all audio until this is fixed.

When you click Edit, the already-compressed file is the one that UE is working with.

Which means you never get to 100% even if you ask for it.

What Should happen is that when you change compression/quality %

1. UE4 should always refer to the original file, you have to always go back to the Best Quality before running any compression, even for a simple UI slider change, which means reimporting every time. It is technically inefficient from a file-import + UI Slider Input Action perspective ( a very valid perspective), but Efficiency Must Give Way To Quality in this case. The inefficiency can be avoided by putting the user slider input on a longer timer, only doing file import once no motion of slider is detected for some time. Or removing the slider aspect and only offering a straight numeric input that requires enter key usage.

Any Engine UI efficiency issue must be improved technically so that

Efficient-Editor-Usage is Not a Barrier to Getting Highest Quality Audio.

2. During % change in UI, check if 100% was chosen, if so, reimport and don’t run compression

3. If a compression quality less than 100% was chosen, reimport and use only the requested compression.

4. Personally, I find 100% a confusing term for compression quality, I would think that 0 means no compression, but the term itself is sort of double, compression-quality. What exactly does that mean? The term makes it sound like compress and quality are a smooth gradient and that they work together nicely. But that is not the case.

It is always compression ~vs~ quality, like a Street Fighter video game in the Life of a Digital File (LDF).

Compression and Quality are ~opposing factors~, not a happy blend from red to hyper-radiant green.

Compression destroys Quality, Quality seeks to survive compression attempts.

And it is all largely unncessary these days, because even hand held devices have lots of storage space.

In the 1900’s I am sure you needed the compression always, but this is the Modern Era and the Bass, which does require large files:

Yields The Best Dance Music.

But for now, to minimize changes, the above alogrithm always checking for 100%, and if present, not compressing at all and just re-importing is the solution for what everyone wants.

Oh Beautiful Epic who is filling the World With Beauty:

The voice of your loving family members, who are Digital Audio Engineering Experts is:

“UE I know what I am doing, if I want to compress my audio I will use ffmpeg or any audio program and do it myself, please trust me, just import my wav32 file (the Zero Compress Case) and leave it alone. Love You!”

I Am Here to Bring the Bass Back

The Very Low Bass frequencies, as everyone is noticing, are being dramatically removed, which is not good for Virtual Music Events,

We Need Bass To Guide Our Dance Moves

I hope Epic sees this and implements my solution. (please see case update below)

In the meantime, I am on the case and will try and do this myself.

Rama Case Update, My 4.27 Experience

Okay this plot just got a lot thicker…

If I try to import a wave32bit file into UE4 4.27, I get this log output:

Error: Unable to read wave file 'CrystalFriendship12' - "Unsupported wave file format.  Only PCM, ADPCM, and DVI ADPCM can be imported."
Error: Unrecognized sound format 'wav' in CrystalFriendship12

I can import a wave32 file in 4.24, but it is heavily affected as we’ve all noted…

How To Import Audio | Unreal Engine 4.27 Documentation.
4.27 help docs indicate:

Unreal Engine currently imports uncompressed, **little endian** , 16-bit Wave (WAV) files at any sample rate (although, we recommend sample rates of 44.1 kHz or 22.05 kHz).

If I was to translate this a little less politely:

Unreal Engine currently DOES NOT support uncompressed, **little endian**, 32-bit Wave (WAV) files at any sample rate.

If an Epic Staff member would like to say my statement is incorrect I would love to hear that, because I reaaaaaally want wave 32 bit sound in Unreal Engine… so much

The good news is that importing in 4.27 is uncompressed:

SoundFactory.cpp line 351

Sound->CompressionQuality = 100;

My Great Wonderment

Even if I succeeded at getting a 32bit wav file to be imported,

Will the sound engine itself play a 32bit file,

if everything else is currently wired for 16bit?

Reminder: No 32bit = not as good bass, and not as good bass = Less Ecstatic Dancers. (LEDs)

I request Epic Aid, and remain Perpetually Optimistic of a Super Ultra Bass Unreal Engine Audio Revolution.

An Epic Audio Revolution to 32bit quality

If Epic really wants to lead the virtual festival space, we need 32 bit quality for the best quality bass and also the highest metallic-sounding tones ( You could think: Electric Guitar without fuzz).

By the way, wave64 also exists, and that would be very nice toooo, for those considering doing this UE Audio Revolution. (UEAR)

The Frontier of Human Happiness: Wave 64 Bit

It is well known, COVID era not good for finding new relationships.

Music has become our main source of bodily Happiness and Joy, thanks to the very low bass and ultra high tones that only wave32 and wave64 bit can provide us with.

My UEAR Hot Pink Provocative (Romantic & Electron-Exciting) Expression of the Great Wish for Joy, that I Surmise Only Epic Can Fulfill:

It is growing by the moment, the Return of Ultra Bass

From analog ultra-bass potential, but not as much organization,

Humanity has come to Digital 16bit, quite a shift!

There was a brief period of time where we had to figure out how to increase hard disk space…

And Now Together we all hold hands as Friends,

Lead by Epic’s Audio Engineers, with their smiling faces,

And Humanity Now Proceeds Forth

Into the Crystal Rainbow Sparkling Dawn of Digital 64bit!

Can you Feel it?

UEAR64 is coming!

32 bit quality is now just the “middle” of the road for the type of digital quality now being used in most DAWS, truly we are already on the way to 64 bit wav files becoming more than normal.

To be truly ahead, and thus merit a new engine release in the UE4.X range, Epic might want to consider supporting wave 64 bit as well (please?).

All I can do now is think Loving thoughts about every audio engineer at Epic and set aside memory address space (Digital Hope) for an Unreal Engine Audio Revolution (UEAR) to more fully support the UE Virtual Festival Movement.

Want A Proof That Higher Range Audio Can Make You Happy?

I thank Disney for this demonstration of the Power of UDRA (Ultra Dynamic Range Audio) that I have augmented with wave 32 bit file quality to increase the dynamic range of the bass and high tones from the original recording, using my audio remastering techniques to extend the weave of the original song into the 32 bit range (yes, thus actually >> using << the extra bit range).

If this sounds fuzzy to you, or you can’t feel the bass, please invest in a better pair of headphones / speaker system.

Yes, this is a multi-part issue, better files and also better analog output equipment.

I guarantee Happiness if you have an adequate sound system to play this file!

Frozen2_YouAreTheOneYouveBeenWaitingFor_IAmFound

If you have a surround sound system, please, oh please, just try this file, you will be so Happy! Help me end the COVID Era with your Happiness!

A Bigger Proof, Electron Field Joy Via Wave 32 Format (May UEAR32 Happen This Year!)

For those of you Lovely Ones who want a slightly Longer Proof of how awesome the wave 32 file format is when the Full 32bit Range (F32BR) is more effectively utilized using my audio engineering techniques,

And as my further contribution to your Happiness for this day and Every Day,

And as another way to smash the COVID era into tiny little pieces of Golden Electron Happiness!

:zap: Smash the COVID era :zap: into tiny little pieces of :star2: Golden Electron Happiness! :star2:

And to Hopefully Inspire (@PresumptivePanda gave me New Hope recently!) the UEAR, Unreal Engine Audio Revolution to wave 32 or even wave 64 support,

Here again, Thanks to Disney and The Goddess Aurora and The Goddess Idina Menzel, is Digital Audio Happiness (DAH) with Very Low Bass Frequencies (LBFs) and Very High Tones (VHTs) that will:

Fill You With Happiness!

Hyper-Radiant Bass For Body Joy

http://lightningfitness.org /EverNewJoySound/Frozen2_IntoTheUnknown_HertzLevelSmoothingForHarmony_RinseAndRepeatAlternatingSignsToTaste.wav

Above is a very a special version, the name explains a bit about my methods!

Procedurally Smoothed at the Hertz Level, in the Bass Track = Body Healing

Yes!

Procedurally Smoothed at the Hertz Level, in the Bass Track = :sparkling_heart: Body Healing :sparkling_heart:

Why are Procedurally Smoothed Hertz-Level Bass Frequencies (LBFs) so Healing for Your Body?

Well quite simply because all the crazy electrical fields in and around our world distort us at the electron field level, and bass frequencies (LBFs) can actually reach our body and heal this issue.

So I am giving your body the same procedural smoothing at the electron field level by using procedural hertz level smoothing.

Basically, your body’s Electron Field is getting the same algorithm of hertz level smoothing that is being applied to the hertz level of the audio file.

And with the refinement that wave32 alone affords me

The hertz level smoothing is sufficiently precise to affect your Electron Field.

(Important Note: Please be sure to actually download my files, if you try to listen in a web browser, the streaming bitrange is smaller than wave32 bit in Chrome at least (until they fix it), so you will only get the Best Sound if you download the file and play locally, hopefully in a Surround Sound System)

Activating Your Electron Field

The goal of my audio engineering is to use the wave32 format to tease the electrons of the Electron Field layer of your body, which in turn gives you energy, so basically almost Free Energy, for the expense of your electric bill to run your computer to play this file!

But since most of you are already paying your electric bill anyway, it is indeed Free Energy in digital audio form, relative to your current lifestyle (using Unreal Engine on a frequent basis)!

Absolute Proof That Wave32 Is Necessary, Why the UEAR32 Must Occur For Happiness To Win On Planet Earth

You can really hear the difference that wave32 affords, because if you play the file in browser, it sounds fuzzy and strange.

But if you will please download the file,

You Will Get Free Energy from me via

Electron Field Excitation!

Yes!!!

PSS: If you are thinking “Rama I don’t get any of this, it sounds normal to me”

You need a better sound system Dear One!

How will you know if you got the right equipment?

If You can FEEL the BASS you got a good system!

Buy a fancier headset or get a surround sound system and you will have Free Energy and Digital Audio Happiness (DAH) from me, to Fuel Your Electron Field for Life!

Yes that is the only requirement of Health and Healing = Sufficiently Fueling Your Electron Field

A Spiral Of Excited Electrons Interacting, Excited by Mutally Friendly 2 Channel LFBs

PSSS: I am sure at least one of you who likes to make motors can think of a way, using the principles I’ve described above, to design a certain kind of machine that will absorb the miminal cost of playing these songs into speakers facing each other (Spiral of Excited Electrons Interacting between speakers)

And yes the original file has split channels (stereo, 2 channel), so the speakers are NOT playing exactly the same thing… but they are Friends.

And the result is a > 1,

WAY better than Unity energy output

WAY better than Unity

(you are getting more out than you are putting in)

Just, ahm, be careful when you turn the thing on please

Start with the volume low!!! Raise the volume gradually and enjoy the Rainbow Lightning Colored Sparks Show!

And maybe film the whole event and post it for us here!

Rama’s Greatest Proof of the Power of Wave32bit & Rama’s Favorite Disney Song Ever

Dear Unreal Engine Community,

I present to you now, my finest digital engineering work so far, as inspired by my favorite Disney theatrical performance,

For you can really FEEL The Goddess Idina Menzel giving Her Whole Body Voice and Soul to this Performance.

Disney is my favorite purely Entertainment company! (ever since I was little)

Epic, I think of as having other roles besides just entertainment, mainly:

Empowering Our Creativity.

And this song I am sharing with you as a proof of why we need wave32bit, to truly reach new Heights and Depths of Happiness, is my favorite Disney Song Ever!

So, Dear Goddess Idina Menzel, whenever You read these words, please know that me saying this is my favorite theatrical performance by my favorite Entertainment company is me trying to indicate that what You have achieved in this performance, Oh Goddess, is literally Beyond This World.

In fact, when I meditated today as I always do to get inspiration for my Creative Activities, the Angels informed me that this performance of Yours, Oh Goddess, is Famous All Over Creation.

Yes, Oh Lovely People of The UE Forums,

Idina Menzel is a Cosmic Rock Star Goddess because this performance!

So of course I went all out with my digital audio engineering for this song!

The result being that this has become my greatest proof of how much we can achieve when we can use wave32bit natively in Unreal Engine.

As is true of any UFR (Unusual Frequency Range) experience, at first you may find some part of you resisting my wave 32bit enhanced version of the song.

Please be patient and loving with yourself, and just let the song play, and choose to focus on whichever aspects of the song interest you the most at any given moment.

With such an Ultra Dynamic Range of Sound to enjoy, you have an Abundance of aspects of the song to focus on, which does make it easier to adapt to the UFR.

Just enjoy, go with the Flow of Fun, Relax Into the Music,

And let the Voice of the Goddess Idina Menzel Carry You, Hold You, Love You, and Comfort You.

A Gift to Epic

So I present this song to you as well, Friends at Epic, and also our Dear Friend @PresumptivePanda, as my final proof, for now, of why we really do need wave32bit natively in UE4 and UE5.

I really do remain Perpetually Optimistic, that we can have a UEAR32, Unreal Engine Audio Revolution to 32bit, within this year 2022!

Oh the things I could do,

At no cost to all of you (think Victory Plugin for Audio Engineers), if I could use wave32bit natively in UE.

Oh I got plans! And complimentary plugins in mind, so that all of you can simply press a button to run a variety of the algorithms that I myself am using to create these past 4 wave32bit files.

My techniques are fairly easy to implement, and I could give them to the world… * sniff * … if we had wave32 bit natively in Unreal Engine.

The Power Of The Voice of The Goddess Idina Menzel

Please now, pause your day, relax, get ready for your body to Glow with Rainbow Crystalline Happiness, and please listen as closely as you can, to the Voice of the Goddess Idina.

I guarantee, with each playthrough, you will hear more and more subtle intonations in Her Voice that you didn’t hear the last time!

I do, positively, Guarantee It!

A Message To The Goddess Idina Menzel

Dear Goddess Idina Menzel,

I hope You get to hear this audio, for the Healing Power of Your Voice when augmented with my audio techniques and the wave 32bit file format, results in a Crystalline Transformation of the body and mind of anyone who listens!

I wanted you to know, that the final High Tone You reach at the end of the song, which my wave32bit audio engineering has fully revealed as Beyond Perfection, is so Perfect, that it is a Consciousness-Altering moment.

Friends of the UE Forums, Goddess Idina merges into the Song at the end.

You know what an Orchestral Hit is in music right? When the whole orchestra is playing together in a quick moment?

Goddess Idina, You…somehow… manage with Your Voice, to match the entire Orchestra!!!

Yes, Dear People Who Read This, She Becomes an Entire Orchestra By Herself, acheiving a texture, a tonal range, a complexity of Voice, that I honestly didn’t think humans or even Rainbow Unicorns could achieve.

So, Goddess Idina Menzel, congratulations on bringing us a Cosmic Victory.

A Sound that can Merge You, The Listener, into the Music.

A Guaranteed Moment of Healing and Inspiration!

As Goddess Idina uses what could only be Her Own Magical Rainbow Unicorn Powers to morph Her Entire Voice into the sound of the Whole Orchestra, matching so many instruments and so many performers… all by Herself!

Yes the Voice of the Goddess Idina is Magic,

I ask that any of the nearly-infinite Hyper-Intelligent Beautiful Goddesses who use Unreal Engine on a daily basis who see this, to please make sure Idina Menzel sees this post and gets to hear this wave 32bit version of what is considered our Cosmic Victory, not just a planetary victory, by the Angels who reported this fact to me.

A Sound That Can Heal All

This is a less than 100mb file that can Heal The Entire Cosmos With Harmony.

And Thank You, Goddess Evan Rachel Wood, for some of the most powerfully emotionally healing tones I’ve ever heard, Your Goddess Voice , toward the end of the song, which make me feel better every time I listen to You sing!

~ Cosmic Victory, a Song To Heal The Whole of Creation ~
You Are The One You’ve Been Waiting For ~ I Am Found ~ Show Yourself!
Starring: The Goddess Idina Menzel,
Who Shook the Cosmos With Her Voice in This Song,
A Rainbow Crystal Unicorn,
and The Goddess Evan Rachel Wood

Please, Goddess Evan, Be Happy… the Rainbow Crystal Unicorn only got 2nd place seating in the credits because She had to concentrate so hard to run over that water for so long, while protecting our Dear Goddess, Idina Menzel.

You know, It’s not that easy to run over ice-cold Atahallan ocean waves at high speeds, while maintaining a smooth ride for the Goddess Idina’s Cosmic Victory Performance.

So, Rainbow Crystal Unicorn Nuzzles You Gently and hopes that You, the Goddess Evan Rachel Wood, will forgive Her Joy of getting 2nd place in the credits. She’ll even give you a Ride Home if you want!

The Wave 32bit File Itself, Proof of The Joy of the Coming UEAR32

Please copy/paste into url and remove the space, the forums are not posting audio links in a player that actually works, so I have to do this instead.

Download The File For Joy, Surround Sound System For Life Transformation to Happiness and Fun

Also, please remember to please download the file, the sound will be truly strange to you if you try to stream the file above in an internet browser!

I highly advise pausing the song as soon as it starts and giving the Goddess Idina’s Cosmos-Changing performance a real chance with your ears, by just pausing the song as it starts, downloading, and THEN listening.

A Powerful Sound System Is Required For A Cosmos-Changing Song

Please don’t pretend you can play a wave32 bit file on a hand-held device!

Anything less than a PC is just a joke when it comes to audio.

The song will sound tinny and weird on a cellphone.

You need a powerful sound system, very good headphones, or a Surround Sound System, or even Bigger Systems, and then you will experience Real Joy from listening to this audio file!

How to know if your sound system is good enough?

The Bass (Very Low Frequency Tones) will sound Deep and Full, hitting tones you usually only hear when people are playing really loud bass while passing you in cars, until the roof of their car flies off because the ultra intense bass caused the roof-screws to unscrew themselves (this has really happened!).

That’s good Bass!

Oh How Happy You Will Be!

I hope this song brings you Happiness, Fun, and Joy!

I would love it if listening to this song becomes a Friendship Event for you,

As you gather Together at the house of whoever has a Surround Sound System.

Or you could all pitch in and buy one Together!

Yes, that is how we enter The New Time of Friendship and Laughter in this world!

By Gathering Together Again,

Dancing,

Having Fun, and Laughing Together,

As we listen to the Goddesses Sing To Each Other in Disney’s Frozen 2!

Goddess Kristen Bell’s (Princess Ana’s) performances boggle my mind as well!

Goddess Kristen’s Voice is So Sweet While Also Being So Unstoppable!

Finally, Oh How Happy I Hope This Song Makes You, Dear Great Goddess Idina Menzel!

Your Goddess Voice , heard by even a few people in this wave 32bit song file,

Will Spread Around The World…

And Heal All

[Arrerong]

@Rama One user mentions a -3db attenuation that UE4 applies by default, this seems to be a thing in UE5 as well. Do you or anyone else know how to disable this? It’s driving me crazy that my sounds aren’t as loud as I’ve mastered them to in my DAW.
