Is this what it does?
Of course. You are not going to send mp3-encoded audio over a phone line, are you? That would require an mp3 decoder in every phone. In fact, any mp3 player is transcoding to linear on the fly, since that is part of converting it to audio for the speaker or earphones! What did you think was the difference between "trascoding to slin" and "playing the mp3"? > Also, does this mean I might as well change the format of MP3s to WAV > seeing as I'm used to doing that anyway? If you have the storage space available for the larger WAV files, then yes, this would reduce the CPU consumption of playback.
