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!
1
+ A current list of the features we will not implement is kept on the wiki:
4
2
5
- Q2. Record to WAV (uncompressed) or MP3pro format!
6
- A2. The recording hardware (the MAS) does not allow us to do this.

8
- Q3. Crossfade between tracks!
9
- A3. Crossfading would require two mp3 decoders, and we only have one. This
10
- is not possible.
5
+ Additional information is available here:

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.
27
-
28
- 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.
32
-
33
- Doing the conversion with the CPU is impossible, since a 12MHz SH1 is far
34
- too slow for this daunting task.
35
-
36
- 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.
