Jukebox Recorder 20 record in lossless?

[jbills]

This is fantastic - will be a huge asset to us "old school" archos users!  I can't believe my little ondio is an uncompressed recorder now.  HUGE!

hey, it's working for me, but the only question I have - how do you control the input gain?  the recordings I just tried weren't clipping or anything, but I just can't wrap my head around recording without gain controls.  anyone know?

[pixelma]

At the moment you can't control the gain from within the plugin but: wavrecord will use the gain you set in the recording screen; just set it there before starting the plugin. It's not very user friendly but this exists as a plugin to demonstrate that the feature works and one can already use it. The plan is to have it integrated in the core as "just" another recording setting, *one day*.

I can't believe my little ondio is an uncompressed recorder now.  HUGE!

You probably already noticed that wavrecord will only record to the MMC because those usually have more storage than the internal memory. Due to the fact that write speed can vary a lot between cards, there is a possibility that wavrecord can fail on one or the other - you'll notice that the filesize won't increase anymore at the point where it just can't write the data away fast enough; but you can still turn it off. For me one of my MMCs isn't fast enough, the other is.

P.S. Yes, yes, I know. I'll put that wiki page up tomorrow and hopefully start the tex file for the manual.

Incredible!  thank you thank you thank you for this, and for the explaination.  Will definitely put this to use - LOTS!  especially once it's integrated into the core.  Thanks again.  can't say that enough.

This is really big news!!

I made some test recordings with wavrecord this weekend (via internal mic and via SPDIF) and it worked like a charm!

Since the file size of a single recording is limited to 2 GB by the file system, it is possible to record up about 3 hours (@ 48 kHz, stereo) or 3 hours, 15 minutes (@ 44,1 kHz, stereo) at a time. This should be sufficient for most purposes...

Has anybody tried if the batteries allow recordings of 2 or 3 hours? The hard drive of my Recorder v1 (with 8MB RAM mod) spins up about every 40 seconds while recording in WAV format, so it might drain the batteries faster than recording in MP3 format. On the other hand, the MAS chip probably eats less power if it does not have to encode in MP3 format!?

Many thanks to everyone involved in the WAV playing and recording plugins! You did a great job!

I agree, great Job. 8-)

The hard drive of my Recorder v1 (with 8MB RAM mod) spins up about every 40 seconds while recording in WAV format, so it might drain the batteries faster than recording in MP3 format. On the other hand, the MAS chip probably eats less power if it does not have to encode in MP3 format!?

I suppose that a hard disk spinning up consumes more energy than a MAS encoding MP3 in realtime, since the MAS is specialized to do the encoding with low battery usage.

I'm really looking foward to see the WAV recording feature integrated into the core recording system of Rockbox. If Rockbox monitored the file size and began a new file after reaching 2 GB it would be perfect.

But neveretheless the wav plug-ins are more than I've ever dreamed about.

I tried to download PCM microcode into MAS3587F (according to PCMAudioRecorder_Documentation.pdf) but without success -  seems that chip hungs on any command after call to mas_run(0x1000) ;
Is anybody else working on PCM playback for Archos? Or there is no hope...

Regards,
Max.

I've exactly same problem, the chip hangs after the run command. Do someone else get it working ?  

Thanks in advance,

I'm not sure what you are trying to achieve here, but both plugins are now in SVN - wavplay and wavrecord.

If you want to write your own code or plugin, you could take a look at the source of these two (both are in apps/plugins).

[freud]

Thanks for your reply !

Yes, I'm working on a new hardware based on MAS3539F Decoder chip, decoding and encoding part (ADPCM) works fine from/to an SD memory card. My main processor is a NXP LPC2378 (ARM7 CPU) which handles man machine interface (LCD, rotary encoder, USB mass storage, Ethernet TCP/IP, SD card driver and bitstream to/from the micronas chip). The project is working except to few bugs to be fixed. I saw a nice plugin from the Rockbox project which allow the WAV record/playback (PCM code provided by Archos) and I would like to test it on my hardware (recording part in WAV rather than ADPCM is a nice feature since I'm a guitar player and need to get highest sound quality).

I studied the plugin code (PCM Audio Recorder) and my code is similar to the RockBox ones. After transferring the PCM code, I got same issue as Max90125.. the MAS chip hangs after a Run Command   I'm pretty sure the MAS DSP core is same between MAS3539F and MAS3587F chip (they are both same pinout though, so it's easy to swapf one by the others )

My other solution would be to use the I2S interface in my ARM7 to connect a nice codec (DAC/ADC) to play/record wav. As I found out the MAS could do it, I prefered tested before but with no success...

hello!  recently recieved a loanaer AJB20 (old) and tried using wavrecord.

it works for about 10 seconds, then i get his message....

any ideas?  im new to rockbox.

thanks in advance!

edit : it freezes up when i try to record in mp3 as well.

maybe a bad hard drive?

it seems to happen around 1 meg of recording.

[scoz]

wow.  I'd given up hope when the last time I looked for this thread it had dissappeard.  (It was in my bookmarks for ages, I presume there must have been a messageboard software update or something since my bookmarking it)

[heyitsmejess]

ive got it working now.

just and fyi - i got 90 min out of cheap alkaline batteries recording in wav

Hello
Where can I find a release or plugin to record in lossless ?
Thank

Olivier

[petur]

all plugins are included when you install/upgrade RockBox

[kersu]

I have put french language in my archos, an i did'nt understand
"Plugins > Applications > wavrecord", I thought it was a old link or other

Now, all is allright
Thank you
