Much respect to the devs for all their work in implementing mp3 recording. I've been using .wav and probably will continue to do so, but it never hurts to have more options. But either the mp3 recording still needs work or I am doing something wrong.
I just downloaded the 0902 build and tried recording with mp3 at 320 kbps. With Line-in as the source, I plugged a dinky microphone into a battery module and spoke a little bit.
On playback, it was quiet of course, but although I had AGC off, the speech was accompanied by hiss--as if it was boosting the speech--with silence in between words. Words were also cut off entirely at a certain threshold, so it was either voice-with-hiss, with words clipped off, or silence.
.wav recording had neither the hiss nor the sudden contrasts, and I hadn't changed the AGC setting.
Is it possible the mp3 recording is automatically adding AGC? Or is this a compression artifact, even at such a high bitrate?
