Hi, I recently acquired a cheap chinese MP3 Player with voice recording/encoding capability.

The max voice quality you can get from this is "IMA ADPCM 16bit 32kbps mono".

I downloaded some voice encodings from the player and opened them with Adobe Audition, edited useless parts and saved as the same format.

There is supposedly a re-encoding process going on, but I can´t notice any quality degradation. I really don´t want to save to plain PCM because, correct me if I´m wrong, the files would be 4 times bigger (I already tried with approximately 4x size increase).

What would you do to preserve as much quality as possible without increasing the size (I mean keeping it around the same bitrate)?

Thanks.

Edit: it was actually 32kbps
