···1-Q1. What is this NODO document?
2-A1. This is a list of Feature Requests we get repeatedly that we simply
3- cannot do on the Archos. View it as the opposite of a TODO!
4-5-Q2. Record to WAV (uncompressed) or MP3pro format!
6-A2. The recording hardware (the MAS) does not allow us to do this.
7-8-Q3. Crossfade between tracks!
9-A3. Crossfading would require two mp3 decoders, and we only have one. This
10- is not possible.
11-12-Q4. Interfacing with other USB devices (like cameras) or 2 player games over
13- USB
14-A4. The USB system demands that there is a master that talks to a slave.
15- The Archos can only serve as a slave, as most other USB devices such
16- as cameras can. Thus, without a master no communication between the slaves
17- can take place.
18-19- If that is not enough, we have no ways of actually controlling the
20- communication performed over USB since the USB circuit in the Archos is
21- strictly made for disk-access and does not allow us to play with it the
22- way we'd need for any good communication to work.
23-24-Q5. Support MP3pro, WMA or other sound format playback!
25-A5. The mp3-decoding hardware can only play MP3. We cannot make it play other
26- sound formats.
2728-Q6. Converting OGG->MP3
29-A6. The mp3-decoding hardware cannot decode ogg. It can be reprogrammed, but
30- there is too little memory for OGG and we have no documentation on how
31- to program the MAS' DSP.
3233- Doing the conversion with the CPU is impossible, since a 12MHz SH1 is far
34- too slow for this daunting task.
3536-Q7. Archos Multimedia support!
37-A7. The Archos Multimedia is a completely different beast. It is an entirely
38- different architecture, differnt CPU and upgrading the software is done a
39- completely different way. We do not venture into this.
40-41- Others may do so. We do not.
42-43-Q8. Multi-band equalizer!
44-A8. The MAS only offers the standard bass/treble settings and we can't do
45- anything about it.
46-47-Q9. Support other filesystems than FAT32 (like NTFS or ext2 or whatever)!
48-A9. No.
49-50- Rockbox needs to support FAT32 since it can only start off a FAT32
51- partition (since that is the only way the ROM can load it), and adding
52- support for more filesystems will just take away valueable ram for
53- unnecessary features.
54-55- You can partition your Archos fine, just make sure the first one is FAT32
56- and then make the other ones whatever file system you want. Just don't
57- expect Rockbox to understand them.
58-59-Q10. Add scandisk-like features!
60-A10. It would be a very slow operation that would drain the batteries and take
61- a lot of useful ram for something that is much better and faster done
62- when connected to a host computer.
63-64-Q11. CBR recording!
65-A11. The MP3 encoding hardware does not allow this.
66-67-Q12. Change tempo of a song without changing pitch!
68-A12. The MP3 decoding hardware does not allow this.
69-70-Q13. Graphic frequency (spectrum) analyzer!
71-A13. We can't access the audio waveform from the MP3 decoder so we can't
72- analyze it. Even if we had access to it, the CPU would probably be too
73- slow to perform the analysis anyway.
74-75-Q14. Cool sound effects!
76-A14. Adding new sound effects requires reprogramming the MAS chip, and we can't
77- do that. The MAS chip is programmable, but we have no access to the chip
78- documentation.
