wmorrow I purchased record pad and SWITCH in order to enable attachments of audio files to emails. I am having trouble finding the right format and file size to do this.
nchtj if its voice recordings, save to .wav using the GSM 6.10 codec, 8000Hz, mono if its music, save to mp3, and depending on what quality you want, try encoding at somewhere between 64kbps to 128kbps.
