Daniel Stenberg | 09768f6 | 2003-01-16 16:06:31 +0000 | [diff] [blame] | 1 | Q1. What is this NODO document? |
Daniel Stenberg | 8a6d963 | 2003-01-16 16:06:58 +0000 | [diff] [blame] | 2 | A1. This is a list of Feature Requests we get repeatedly that we simply |
Björn Stenberg | 0b23c48 | 2004-09-17 07:16:09 +0000 | [diff] [blame] | 3 | cannot do on the Archos. View it as the opposite of a TODO! |
Daniel Stenberg | 09768f6 | 2003-01-16 16:06:31 +0000 | [diff] [blame] | 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! |
Daniel Stenberg | 379416d | 2003-01-16 16:29:29 +0000 | [diff] [blame] | 9 | A3. Crossfading would require two mp3 decoders, and we only have one. This |
Daniel Stenberg | 09768f6 | 2003-01-16 16:06:31 +0000 | [diff] [blame] | 10 | is not possible. |
| 11 | |
| 12 | Q4. Interfacing with other USB devices (like cameras) or 2 player games over |
| 13 | USB |
Robert Hak | 6e3eb84 | 2003-02-21 23:40:31 +0000 | [diff] [blame] | 14 | A4. The USB system demands that there is a master that talks to a slave. |
Daniel Stenberg | 09768f6 | 2003-01-16 16:06:31 +0000 | [diff] [blame] | 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 | |
Daniel Stenberg | 379416d | 2003-01-16 16:29:29 +0000 | [diff] [blame] | 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. |
Daniel Stenberg | 09768f6 | 2003-01-16 16:06:31 +0000 | [diff] [blame] | 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 | |
Linus Nielsen Feltzing | 7b70346 | 2003-05-03 13:00:25 +0000 | [diff] [blame] | 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. |
Daniel Stenberg | 09768f6 | 2003-01-16 16:06:31 +0000 | [diff] [blame] | 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! |
Linus Nielsen Feltzing | 0600cb1 | 2004-05-29 12:42:49 +0000 | [diff] [blame] | 68 | A12. The MP3 decoding hardware does not allow this. |
Robert Hak | b674585 | 2003-04-28 20:52:47 +0000 | [diff] [blame] | 69 | |
Linus Nielsen Feltzing | cc16b50 | 2003-05-09 16:22:53 +0000 | [diff] [blame] | 70 | Q13. Graphic frequency (spectrum) analyzer! |
| 71 | A13. We can't access the audio waveform from the MP3 decoder so we can't |
Linus Nielsen Feltzing | 7b70346 | 2003-05-03 13:00:25 +0000 | [diff] [blame] | 72 | 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 Feltzing | cc16b50 | 2003-05-09 16:22:53 +0000 | [diff] [blame] | 75 | Q14. Cool sound effects! |
| 76 | A14. Adding new sound effects requires reprogramming the MAS chip, and we can't |
Linus Nielsen Feltzing | 7b70346 | 2003-05-03 13:00:25 +0000 | [diff] [blame] | 77 | do that. The MAS chip is programmable, but we have no access to the chip |
| 78 | documentation. |
