1 | Q1. What is this NODO document? | 1 | A current list of the features we will not implement is kept on the wiki: |
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 | 2 | ||
5 | Q2. Record to WAV (uncompressed) or MP3pro format! | 3 | http://www.rockbox.org/wiki/NoDo |
6 | A2. The recording hardware (the MAS) does not allow us to do this. | ||
7 | 4 | ||
8 | Q3. Crossfade between tracks! | 5 | Additional information is available here: |
9 | A3. Crossfading would require two mp3 decoders, and we only have one. This | ||
10 | is not possible. | ||
11 | 6 | ||
12 | Q4. Interfacing with other USB devices (like cameras) or 2 player games over | 7 | http://www.rockbox.org/wiki/NoDoDiscussion \ No newline at end of file |
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. | ||
