Recording is now with Mp3 support !

[MoAv]

Well they've done it, my player is complete.
Check out the new daily build and you'll see a small surprize called multi bitrate mp3 recording support for your sweet player. As you can imagine I was waiting for this option for a longggg time now.
Update is a must !
Oh and there's something new with the FM recording, but who cares ...
Thanks Devs !

P.S. if I had playable FF/RW I could retire completely from waiting to the official FW.

omg sweeeeet

thanks mods!

Awesome. I was thinking I might want to record some voice memos while I'm on my upcoming trip to Europe, but CD quality would be so wasteful!

I'll have to test it out. That's awesome.

Works like a charm, though I think they need to work on the efficiency part.
It seems to be needing high computing rate cause my battery is loosing allot of strength pretty quickly.

[kermix_h120]

Yeah, that's not a surprise. I remember it being said that realtime encoding just couldn't be done, period, because of the processing requirements. I was surprised to see it at all.

If iRiver made it happen on the stock FW so it must have been thought to be possible.
Not only it was possible, I took some long time recording under the old FW with 192Khz mp3 compression recording and it was way better conserving battery power then the RB, mabey up to 1/2 the hunger, so I can surely see a room for improvement.

Much respect to the devs for all their work in implementing mp3 recording. I've been using .wav and probably will continue to do so, but it never hurts to have more options. But either the mp3 recording still needs work or I am doing something wrong.

I just downloaded the 0902 build and tried recording with mp3 at 320 kbps. With Line-in as the source, I plugged a dinky microphone into a battery module and spoke a little bit.

On playback, it was quiet of course, but although I had AGC off, the speech was accompanied by hiss--as if it was boosting the speech--with silence in between words. Words were also cut off entirely at a certain threshold, so it was either voice-with-hiss, with words clipped off, or silence.

.wav recording had neither the hiss nor the sudden contrasts, and I hadn't changed the AGC setting.

Is it possible the mp3 recording is automatically adding AGC? Or is this a compression artifact, even at such a high bitrate?

[MoAv]

I've done some tests on this recording new feature, as many other did, and I didn't encounter ANY problem with sound quality.
Been using the int. Mic for the test and did mostly whistling and talking ( is it to myself if my H140 is listening ? :/ )
Check to see if it's not your battery powered Mic that causing it. Oh and bring it up on RB forum.

Oh and keep your pulse with the progress of this feature, much of those bugs are being fixed on a daily basis, if you might use this feature update your FW constantly until feature is bug free.

Thanks, Moav. It's not the mic because there were no problems with recording exactly the same setup to .wav. That mic and module have recording hundreds of hours of concerts (and yes, the battery is working).

What it sounded like to me was that AGC was enabled, even though it wasn't.

I'm definitely not ruling out user error, but I will also contact Rockbox.
