Has anyone noticed an accuracy difference between .mp3 and higher resolution files when analyzing and detecting note and Key for songs?

 

seems like wav and mp3 both work. if for some reason your song has something in the high end that gets chopped by mp3 it wont get detected but thats rare.

try scaler, ez keys, ez bass detectors too. they have a pretty unique algo that seems to average what they detect. for more granular try neural note or melodyne

 

Didn't tested.

But with low quality MP3 (like 128k), there is a distinct "wobbling" effect, changing pitch.
There is less stereo separation too,missing freqs ...
But only on low quality.

 

Most of my .mp3 files are 256 kbp.

 

So it should not a make a difference

It is easy to test : take an original WAV, do the detection.
Convert it to MP3 256 and do the same detection.

Problem with most MP3 is you never know the source.
It is more related to MP3 quality itself than MP3 compression.

 

EDITED：
I deleted it because it seems to be a little different from this thread.
excuse me.

Not a lick of a difference for note detection.

 

what a stupid reasoning, most common (<~8th octave) notes' harmonics operate on too low frequencies for normal (>112kb/s, >32kHz samplerate) audio quality factor to be even considered as error
all audio software is converting mp3 to wav due to speed

 

Of course .wav is better sound quality, but does it matter for note detection?
