Topic: Iriver Question

[Cheesecadet]

Hey all after searching all over the place i came up with two conflicting reports...so...

Does the iriver 120/140 allow you to record at 16-Bit/ 48 kHz ....OR....Only  16-Bit/ 44.1 kHz???

Assuming the unit is rockboxed of course

If I remember correctly, you can do 16/48 if running analog in, digital in it'll read the 48k signal as 44.1 - causing major speed issues.

I had this problem as well, but it was caused by the 9-13-2006 REP build I was using. Other builds of RockBox will accept up to 16/96 via optical. I'm using a much older build, so I can't really say if builds currently available on RockBox have this problem or not.

in h1x0, analog in goes up to 16/44, digital does 16/xx (can't remember, could well be 16/96).
Afaik, the invalid samplerate bug was fixed months ago...

on iaudio X5, rockbox does analog 16/88

Can anyone explain the advantage of recording at a higher sample rate if bit-depth is still 16?

Is there no one on this board able to answer this simple question?

I may be mistaken, but, I was thinking that boojum was refering to Ryan Sims question, and not the original question at the top of the thread.  It would have helped clarify the issue if Ryan's post was quoted in his post.  I don't think the benefits of higher sample rates is really discussed in the FAQ, but correct me if I'm wrong.

[Ryan Sims]

You're correct about the sample rate question.  I am still interested if anyone cares to explain.

[Digital Quality]

Are you talking about analog in or digital in?

It will capture as high as 88kHz (possibly 96kHz) 48kHz on the digital in but it puts 44.1kHz in the wav header so it will play really slow in some tools. You can edit the wav header and change it to the right value and everything is cool again.

[Digital Quality]

Never mind. I ran it 88kHz and got dropouts. Looks like 48KHz is the max.

That wasn't the case last time I tested digi-in (quite a ways back, mind). Recorded up to 88kHz fine.

Maybe I had a cable problem, that's entirely possible. I'll test it at home tonight some more with a new cable. It seemed to run fine for a while and then get a drop about every five minutes or so.

If you do find it is a RockBox issue, could you please post it in the recording subforum of rockbox.org (http://forums.rockbox.org/index.php?board=26.0), and/or add it to the bug-tracker (http://www.rockbox.org/tracker/newtask/proj1)? I'll make sure jhMikeS sees it
AFAIK he tested this and so it should work, but I have no h1x0 so I can't try myself...

EDIT: I got told 96kHz works good so no reason 88kHz shouldn't work.

Which build was used when you got the dropouts?
I never had dropouts on my recordings using the 20070217 build + REP from Mmmm´s website .
