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.
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?
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
It would be so nice if after 20 years people would finally embrace AAC/m4a finally.
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).
awesome thanks
IOS shortcut
You do need ashell mini app

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.
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.
@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:

Edit: A more recent blind test, comparing different AAC encoders:

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.
