Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Wav file to MP3 converter app?
i’m working on an arduino project that has an audio element to it. and it needs files to be mp3 format. are there any iphone apps that can do this conversion?
Comments
Twisted wave, ferrite are two off the top of my head.

One free, one partly free (or subscription) and both can handle lots of conversions.
Very sad that AudioShare does not support MP3, @j_liljedahl
Yep I was gonna mention that one and then I remembered it doesn’t do MP3.
It plays MP3 but does not convert to MP3. I could look into adding it if I find a suitable free/open mp3 encoding library with AppStore-compatible license. But who uses MP3 these days?
Oh, I think many people - also I see such question again and again in this forum.
MP3 is still the standard for mobile music for lots of people, I believe... even if there are more modern alternatives, not all music players (hardware or software) may support them.
Or, those people want to have just the same sort of files in their library.
The standard App was "lame" in my times, but I don't know about it's license.
The encoding part of LAME should indeed be compatible with the App Store:

I just bought AudioShare and would definitely welcome the option to convert wav to mp3 there. Thank you in advance
I am surprised to see that the latest release version is from September 2017.
This encoder was a big thing on https://hydrogenaud.io, many years ago 😅
But then, I think this software is simply finished and has all features possible already implemented.
It would be so nice if after 20 years people would finally embrace AAC/m4a finally.
As far as I understood, AAC is better than MP3 at rates of 128kb/s or lower.
If you want the whole quality of a lossy format and don't care much about the space required, you could use "lame" with VBR encoding and -V0 option and this should not be worse than any AAC encoding.
It may be larger, but not much I think. May try a test 😅
And staying with MP3 has it's merrits, as you can just continue to use your old line of Apps to get things encoded (EAC comes to mind), labeled, tagged, loudness balanced, album balanced and so on!
AAC/m4a is generally superior at all but rates compared to mp3 with encoding settings set correctly not just at low bit rates.
Is it a bit less common these days, but some (myself included) do still use it occasionally. And some more often than that. And it’s not super common amongst other file converters so I’m sure it would be appreciated by many. (If possible and isn’t too much work that is).
I hear this from time to time, but never saw a proof.
But there where several proofs that showed the opposite!
One of them:
https://www.sageaudio.com/articles/aac-or-mp3-whats-the-best-lossy-file-type
I think, lame is as good as it get's.
Give it a try 🤗
awesome thanks
Ah, and if I recall correctly, AAC has some strange patent licensing problems in regards to "codecs", which are not clear to me.
I saw a link to this page with details:

INFO
The Sage Audio comparison isn't worth much.
I agree that mp3s enjoy more widespread playback support on different devices but to be fair, the number of recent devices that don't support m4a/aac audio are becoming rare.
Comparing the quality between different encoders by doing volume and null tests is laughable though. It's like judging the quality of a mix by only looking at an oscilloscope without listening to it. Hopefully they don't do their mastering by numbers
I've been compressing my samples to lossy formats for years, starting with mp3, then OGG Vorbis, then m4a/AAC.
The only criterions for me were format support on the devices I plan to use them and subjective sound quality of the encoded file, and even with critical sounds from synths or some percussion instruments, both OGG and m4a were always far better than mp3 at the same bitrate between 128k and 192k.
In the end, I think it's your own judgement that counts. Some people might like the warbly mp3 artifacts!
Codec developers often spend a lot of time doing listening blind tests to optimize their encoding mechanisms and IMO that's the way to go.
@rs2000 I'm not saying that you are wrong, but so far I did not see such blind tests done.
Do you know a website that did such tests in a believable way?
People often see, read or hear what the want to believe ;-)
From my experience, I always used lame with VBR and -V 0 and am simply happy.
But my aged ears will not be able to detect problems - so I may well be totally wrong.
It has probably been 20+ years since, I researched this. At that time, there were tons of articles and demonstrations of the advantages. Keep in mind that there are a lot of parameters that are used that impact the quality of the resulting encoding. At the time that I was looking into the relative merits of m4a/aac/mp4 vs mp3 (it was important for my job), there were a number of people (mostly who had huge mp3 collections and seemed to have a vested interest in dissing other formats) that posted examples of poorly encoded sources...they had either accidentally or on-purpose chosen encoding settings that resulted in poor quality but the problem was their settings not something inherent in the codec.
@espiegel123 Yes, people tend to see what they want to see - or hear, in that case.
But really, I never saw a convincing comparison between max. MP3 files with a good encoder and AAC.
Yes, you get the same or better quality with AAC at around the same or lower bitrates, but is it really better as max. MP3 at some point? For my ears, most probably not - I just cannot hear the difference.
And this may be true for many.
Let's say that AAC is provable better than max. MP3 from 228 kb/s or higher.
Fine.
Can I myself really hear that?
Do I care about 228 vs. 320 kb/s storage usage when I need to replace my encoding pipeline?
Can my old iPod Touch, my car and my Samsung player also play AAC?
As long as AAC is not massively better - hearable by anyone - people may just stick to MP3.
Just trying to explain why people may tend to stick to MP3, still 😅
@tja It's been a while but I guess that you'll still find some information on the hydrogenaud.io forums.
An older detailed result report can be found here:
http://listening-test.coresv.net/results.htm
Edit: A more recent blind test, comparing different AAC encoders:
https://hydrogenaud.io/index.php?topic=120062.0
Thanks, but those are what I posted above - they are not tests of AAC at any rate against a max. MP3 (defined as VBC and -V0 with lame, but maybe the FFMPEG is even better?)
I don't expect MP3 to beat AAC at rates of 128kb/s or lower!
But I suspect that a max. MP3 may be the same experienced quality as any AAC.
At least for most ears.
I am tempted to run my own test - here on the forum.
Which AAC encoder is rated best?
Maybe on all of iOS / iPadOS, Windows, Linux and macOS?
Just in case you know ...
I will do this!
May take a bit time.
EDIT: It already starts with a problem.
My MacPorts installation does not work anymore after the last macOS update.
I'm not sure if and when I will be able to do all the things required (new Xcode, ...)
So maybe I will stay in iOS / iPadOS area for this...
While you're at it, let's get a comparison of "Sound Engine" quality on various DAWs, and especially comparing between Desktop and Tablet. It may be necessary to have a sub-test for "Summing Engines". This is very important.
😉
I already learned, that FFMPEG uses a "lame" library, so it may be true that lame is the best MP3 encoder.
And FFMPEG also seems to have the best free AAC encoder.
EDIT: As it seems, Apple's AAC encoder is better - I just need to find this as App or binary.
I leave this to you as exercise 😉
