Recording via optical-in

[manno]

I checked all my setting and made sure that it was being sent a 48khz signal and it is but still downsampling to 44.1khz no matter what I do. Isn't it hardcoded into the patch to only do 44.1 at this time?

Is not the resulting wav in fact 48 kHz PCM data with just a 44.1 header?
Is not the recored wav time length about 9% bigger and does not the sound have a lower pitch?

I'm not sure but I do know that the picth is lower hence incorrect sampling information. What is the easiest way to edit the header only without resampling? I use Audition.

Update- I used "Adjust sample rate" in audition and set it to 48khz. It looked like it only changed the header instead of resampling. The resulting file is now at 48khz and it sounds perfect.

The SPDIF recording patch never downsamples the data it gets. However, it's very possible that an incorrect WAV header gets written. This can be fixed losslessly. The sample rate that gets written to the WAV is the sample rate the signal has got at the moment you press the record key. There  are probably some bugs as well. I'll fix when I have time and am somewhat less tired of working on it.

Thanks for all the hard work and effort that you have put into this!

What type of cable do I need to send an digital signal into the iRiver?  It looks like a standard 3.5mm but that can't be right, is it?  My digital source is a toslink out.  So is there a toslink to 3.5mm cable.  Is that 3.5mm spdif?

Thank you!

I ran optical in the wild for the first time on Thursday night (Rodrigo y Gabriela for the Irish among us). It all went without a hitch.

Hi,

now it's me who is not gonna let this thread die !

From the IRC:

02.13.21 #       <preglow> this reminds me i need to finish spdif recording before i just abandon it

<whatboutbob> preglow: have you had another crack at optical, or have you given up in exasperation?

  <preglow> whatboutbob: haven't had time

[dwonk]

Can we all chip in and get preglow a fruit basket?  He has come this far, let's help him finish it!

[whatboutbob]

If it were me I'd prefer a carton of beer. ;-)

I've already committed to making another rockbox donation once optical recording is done. *fingers crossed*

He was having another go at it yesterday:

15.22.26 #       * preglow has a final (he hopes) stab at spdif recording

...but no update thereafter, so don't get your hopes up.

What's wrong with the patch ? the recording works perfect for me .

[whatboutbob]

moav: Recordings sporadically fail in a way that's difficult to reproduce reliably. Also if the signal fails the recording hangs rather than ending gracefully, forcing a reset.

Hello all! 

I'm new to this forum. I just bought an iHP-140 on Ebay (I should have done this years ago, but no money :'() and wanted to let you know that I will donate 25€ the day optical-in recording works flawlessly. And I hope I will not be the only one.

So please keep up the good work! (I already registered at Paypal  )

Conratulations on your new player, and may you have many mp3 hours with it. I love my two h140's.

I just think that your statement above is a bit tactless and undiplomatic, you're implying that the teams effort to date isn't worth anything, and you only find optical recording to be of value. Lots of man hours hae gone into rockbox which is comprised of lots of line of code, It isn't just optical recording which has value.

Not to pile on the crap, but I agree with Dunno.
I just held an auction for a bunch of iHP-140 parts, donated $200 to ROCKbox and "suggested" that they get the optical done.

It was not ransom, it was just a suggestion. See? Open source, voluntary, all that hippie jazz. Dig?
