MP3 export bit-rate

• Jan 27, 2015 - 12:42

I think I detect slightly worse quality when listening to the MP3 files I export directly from MS, compared to exporting a WAV file from MS and converting it to MP3 using Audacity.

Audacity allows control over the MP3 conversion bit-rate, but unless I missed it MS does not. An MP3 file encoded by Audacity at 128kbps ends up as exactly twice the size of the equivalent MP3 file exported directly from MS; that suggests MS is encoding at 64kbps?

Is there some way to change the LAME bit-rate setting that MS uses?

64 Kbps is far too low, being equivalent to FM radio quality, which is gritty at best and downright distorted at worst.

Even 128 Kbps is a bit low - I can detect artifacts in high frequency sounds like cymabls and high hats with this encoding rate. (Or at least I used to be able to - sadly I have lost a lot of my highend frequency hearing over the last few years).

I always encode at 160Kbps which is enough to squash the file size considerably whilst maintaining a high degree of audio quality.

If we are going to set a fixed rate then it should be no lower than 128Kbps.

Incidentally when I tried exporting directly from a home build of MuseScore 2 development yesterday, the process hung and I had to stop MuseScore.

WAV export proceeded normally, however.
