New Codec and FM Recording for iAudio and iRiver

[jhMikeS]

Adds compression options and FM Radio in for iAudio and iRiver.  No real changes for iPods and Archos.

[Mmmm]

What does it do?

[Llorean]

It lets you record in various bitrates of MP3 (preset choices, between 64kbps and 320kbps, if I recall), high bitrate WV, and uncompressed WAV.

Realtime, while you record, encoding.

If mp3 recording works good, my H140 will be complete firmwarewize and I'm the happiest man alive.
Great find MikeS !
Can't find the H1xx patch file though ...

Hi! I'd love to be able to record to MP3 on my H120, but I went to your site and didn't see any builds for the iRivers

[jhMikeS]

What does it do?

It doesn't really do anything for HW codec players (Archos) or for iPods (no recording yet) but it should be verified that the bit of shuffling around of code didn't break anything (I'm about 100% positive with the changes there it would be impossible to have broken anything for Archos).

For software codec players (x5, iRiver) it adds codec recording in WAV, WV, MP3. No sample rate control (though the menu is there) yet but that I will work on immediately starting after a commit.

It's been checked on the iRivers and the x5 and works well.

There are seven mp3 bitrate settings: 64, 96,128,160,192,224,320
WV is ~900 kBit/s
WAV is of course 1411 but now uses wav_enc.codec.

To all asking about iRivers I didn't post builds because those have already been checked for me by some kind folks. I really want to commit this to CVS soon and it needs some quick testing on the Archos and iPod to see if the incidental changes hurt anything. You'll have to go patch and build if you want that right now for iRiver or iAudio. The link to the patch has been added to the original message up top.

FS# 2939 has been closed so all you with iRivers and iAudios rejoice!

Does the MP3/WV encoding run in realtime, or is that still being worked on?

[jhMikeS]

In real time...just pick your format and record. WV seems a bit CPU intensive thought but I've had no trouble on x5.

[bk]

Excellent! Thanks for all the work you've put into this.

[jhMikeS]

Antonius Hellmann did the base/bulk of the work. I just made it integrate better.

[bluebrother]

Is there a reason why direct encoding to ogg isn't supported? Has it simply not been done or is it too cpu intensive?

[Llorean]

I'm sure this opens up the opportunity for many codecs to be tried. For example, I could imagine Ogg/Speex being rather valuable in this context.

Very Nice, Thanks, I'm downloading it to my player right now.

Edit: It's great, I have a few small requests. I was wondering if there would be a way to add an option to have it record Mono. Also, if it could be added as an option to chose what output frequency the recording used. With the old Archos Recorder I was able to record hour long sermons that came out to about around 10MB. Right now I record WAV and then use winLAME on my computer to compress it to that size.

The settings I used on the old recorder was Mono, 16k Hz and a bitrate of 32 kbps.

While this is by no means nessassary, I already am using winLAME on the PC, It would be nice to be able to record to the finnished product directly on the device.
