Search for "PCM" : none Search for "WAV" : none only : "18 I don't see you mentioning other file types on your list of ideas. What about supporting those? Pessimist's Answer: At the current time we belive this is not very likely The Micronas chip (MAS3507) decoder in the archos does not natively support decoding and there is very little program space in the player to implement it ourselves. The alternative would be to write a software decoder as part of the RockBox firmware. However, as much as we love our players, the computing power of the Archos (SH1 microcontroller) is not fully sufficent for this need. Optimist's Answer: We can play any format if only we can write code for the DSP to decode it. The MAS 3507 (and 3587) are generic DSPs that simply have MP3 codecs in ROM. We can download new codecs in them and we will be the first to celebrate if we can get OGG or FLAC or anything into these DSPs. Unfortunately, we have no docs or tools for writing new MAS DSP code and Intermetall is very secretive about it. If anyone can help, please get in touch! " I'm not talking about decoding here, since the data are already in the decoded format (PCM). And also no mention of the WAV container that can be seen a ID3v0 (remove the header).
