Daniel Stenberg09768f62003-01-16 16:06:31 +00001Q1. What is this NODO document?
Daniel Stenberg8a6d9632003-01-16 16:06:58 +00002A1. This is a list of Feature Requests we get repeatedly that we simply
Björn Stenberg0b23c482004-09-17 07:16:09 +00003 cannot do on the Archos. View it as the opposite of a TODO!
Daniel Stenberg09768f62003-01-16 16:06:31 +00004
5Q2. Record to WAV (uncompressed) or MP3pro format!
6A2. The recording hardware (the MAS) does not allow us to do this.
7
8Q3. Crossfade between tracks!
Daniel Stenberg379416d2003-01-16 16:29:29 +00009A3. Crossfading would require two mp3 decoders, and we only have one. This
Daniel Stenberg09768f62003-01-16 16:06:31 +000010 is not possible.
11
12Q4. Interfacing with other USB devices (like cameras) or 2 player games over
13 USB
Robert Hak6e3eb842003-02-21 23:40:31 +000014A4. The USB system demands that there is a master that talks to a slave.
Daniel Stenberg09768f62003-01-16 16:06:31 +000015 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
Daniel Stenberg379416d2003-01-16 16:29:29 +000024Q5. Support MP3pro, WMA or other sound format playback!
25A5. The mp3-decoding hardware can only play MP3. We cannot make it play other
26 sound formats.
Daniel Stenberg09768f62003-01-16 16:06:31 +000027
28Q6. Converting OGG->MP3
29A6. 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
36Q7. Archos Multimedia support!
37A7. 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
Linus Nielsen Feltzing7b703462003-05-03 13:00:25 +000043Q8. Multi-band equalizer!
44A8. The MAS only offers the standard bass/treble settings and we can't do
45 anything about it.
Daniel Stenberg09768f62003-01-16 16:06:31 +000046
47Q9. Support other filesystems than FAT32 (like NTFS or ext2 or whatever)!
48A9. 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
59Q10. Add scandisk-like features!
60A10. 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
64Q11. CBR recording!
65A11. The MP3 encoding hardware does not allow this.
66
67Q12. Change tempo of a song without changing pitch!
Linus Nielsen Feltzing0600cb12004-05-29 12:42:49 +000068A12. The MP3 decoding hardware does not allow this.
Robert Hakb6745852003-04-28 20:52:47 +000069
Linus Nielsen Feltzingcc16b502003-05-09 16:22:53 +000070Q13. Graphic frequency (spectrum) analyzer!
71A13. We can't access the audio waveform from the MP3 decoder so we can't
Linus Nielsen Feltzing7b703462003-05-03 13:00:25 +000072 analyze it. Even if we had access to it, the CPU would probably be too
73 slow to perform the analysis anyway.
74
Linus Nielsen Feltzingcc16b502003-05-09 16:22:53 +000075Q14. Cool sound effects!
76A14. Adding new sound effects requires reprogramming the MAS chip, and we can't
Linus Nielsen Feltzing7b703462003-05-03 13:00:25 +000077 do that. The MAS chip is programmable, but we have no access to the chip
78 documentation.
