Ok so i know nothing about audio formats and i need straight answers. First situation: I have some files that are in .wma (128kbps) but my phone can't play it so I'm wondering, if I convert these files to .wav will that result in no damage to the audio quality? Furthermore, if that is a bad idea then should i convert them to mp3 instead and if so what is the *equivalent* of 128k wma in mp3 format? (so i don't lose any quality).

 

My second situation is I am trying to convert some youtube vids and am wondering: if i convert the youtube video to .wav does that result in any quality loss? And if I convert it to .wav *first* and then convert the wav file to .mp3 (320kbps) *second* (simply for space), does that result in any quality damage? If there's a better alternative to doing what i'm trying to do i.e better formats etc. then let me know about that too.

.mp3 is a lossy format . i.e. it throws away data that it considers is being masked by other program content, and should be avoided these days, You should convert them to .wav or .aiff which are lossless , or if you really need to conserve space, then convert them to .flac which can also have quite small file sizes depending on the .flac settings, and retains the full quality of the original recordings.

I am assuming that your phone can play .flac files 

 

 Surprisingly, I have found that converting the audio of low bit rate (128kb/s) .aac audio on YouTube to .wav files using my video conversion software actually results in a small but worthwhile audible improvement at both the low end AND the high end , and this has been confirmed by a few sceptical technical type members of this forum as a result of posted examples .

How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file.

Cool thanks man just to be clear though, so even though a wav file has a ton more kilabytes that doesn't mean it's adding a bunch of empty data and extra noise to the files?

MP3 is way smaller than .wav, partly because of the Data it throws away.

.wav files are a larger size, but can make faithful copies of the original  .mp3 , and can also have a much wider bandwidth than .mp3 , which is needed for high resolution music files .

They can't however make shitty sounding .mp3 recordings sound any better though.

 These days newer Codecs can markedly reduce file size without compromising the source files provided that their data rate is adequate . The maximum bit rate of .aac  audio is normally 529kb/s and sounds very close to a 16/44.1  1,411kb/s .wav file .

A good example of this is the .mp4 codec and more recent H265 video formats which are way more efficient than for example .mpeg2 

 The best thing to do is try converting a few .mp3s to .wav or .flac  and decide for yourself by listening to both .

But I wouldn’t bother turning 128 wma files into wavs- there’s no benefit and they suck up storage.  You could make 320 mp3s if they sound better through your phone (which is not going to be a dramatic improvement).

Many phones play .flac files. All "Android smartphones and tablets support FLAC audio playback so long as they run on Android 3.1 or later"
