63 | The recording hardware (the MAS) does not allow us to do this | ||
64 | \item Crossfade between tracks.\\ | ||
65 | Crossfading would require two mp3 decoders, and we only have one. | ||
66 | This is not possible. | ||
67 | \item Support MP3pro, WMA or other sound format playback.\\ | ||
68 | The mp3{}-decoding hardware can only play MP3. We cannot make it play other | ||
69 | sound formats. | ||
70 | \item Converting OGG $\rightarrow$ MP3.\\ | ||
71 | The mp3{}-decoding hardware cannot decode OGG. It can be reprogrammed, but | ||
72 | there is too little memory for OGG and we have no documentation on how to | ||
73 | program the MAS' DSP. Doing the conversion with the CPU is impossible, since | ||
74 | a 12~MHz SH1 is far too slow for this daunting task. | ||
75 | \item Archos Multimedia support.\\ | ||
76 | The Archos Multimedia is a completely different beast. It is an entirely | ||
77 | different architecture, different CPU and upgrading the software is done | ||
78 | a completely different way. We do not wish to venture into this. Others | ||
79 | may do so. We will not. | ||
80 | \item Multi{}-band (or graphic) equaliser.\\ | ||
81 | We cannot access information for that kind of visualisation from the MP3 | ||
82 | decoding hardware. | ||
83 | \item CBR recording.\\ | ||
84 | The MP3 encoding hardware does not allow this. | ||
85 | \item Change tempo of a song without changing pitch.\\ | ||
86 | The MP3 decoding hardware does not allow this. | ||
87 | \item Graphic frequency (spectrum analyser).\\ | ||
88 | We cannot access the audio waveform from the MP3 decoder so we cannot analyse | ||
89 | it. Even if we had access to it, the CPU would probably be too slow to | ||
90 | perform the analysis anyway. | ||
91 | \item Cool sound effects.\\ | ||
92 | Adding new sound effects requires reprogramming the MAS chip, and we cannot | ||
93 | do that. The MAS chip is programmable, but we have no access to the chip | ||
94 | documentation. | ||
