Huge clipping with stereo sample recording.

Hello,

I hope this hasn't been reported before.
I upgraded from T1 to T2 recently, and noticed that when I record a Stereo sample, if the input clips, then a huge clipping noise appears when I listen to the recorded sample again. It didn't happen with T1. It looks like this (Bass track) :

I recorded in 44Khz, 16 bits. It doesn't happen with mono sample. I know it's not great to use samples that have clipped, but in a lot of cases it's not a problem to me, especially when I just want to record some ideas quickly and don't mind about the sound quality. But this clipping sounds unbearable, and I guess my speakers don't like it too...

Is it a known bug ?

Thanks.
Julien.

No, never seen that before. It doesn't happen here, I just checked. :?

It looks to me like the overs have 'wrapped around' rather than be clipped to full scale.. but I would be more inclined to blame your soundcard for that rather than Tracktion. What card are you using? You changed drivers or anything recently?

To be honest though, clipping the input is a pretty bad idea to begin with. I would recommend recording at 24 bit if your card supports it, and leaving planty of headroom when recording.

ok i did a test between T1 & T2

a can recreait it here but the cliped files from t1 & t2 seem to sound the same here (but i did clip the input quite high)

i also inported the T1 cliped recording to see if it looked the same, it didint

Thanks for the replies.

My soundcard is the EgoSys Waveterminal 192M. I didn't change anything in my setup recently, all drivers are updated.

I tested in Tracktion 1, it doesn't clip like that. If I load in T1 the project with the clipped sampled of T2, it still sounds terrible (which is logical). But if I record a clipped sample in Tracktion 1, it sounds as a 'normal' clipping sample.

I know it's a bad idea to use clipped sample, but like I said, when I record some quick tries I don't care. And when I record bass it tend to clip very often, but it doesn't mean it will sound distorted.

Subz: want to raise it as a bug if you can recreate it? Still doesn't happen here..

Yeah, I can't repro either. What are you doing subz?

i just set the pre amp on my mike up by 5db (well half way, its normaly ot the bottom)


then ran to the booth & shouted at my mike (verry refreshing feeling :lol: )


& got the same pic as shown above (note to see the clip you have to zoom it to a verry tight vue)

but on the 2 tests i did T1 & T2 thay both sounded the same, just looked diff :shrug:

but it looks like this one is on my head, so over the weekend ill do a full peak record workout & send you the arkive ben

Did it sound distorted, or really broken? Wrapping like the top picture should sound badly wrong.. :scared:

<edit> I mean like speaker-damaging type wrongness! try clipping Synthmaker's outputs if you want to know what I mean.. :hihi:

Post

it just sounded distorted to me :shrug:

but i only spent 5 min's testing

ill do a proper test & log my findings on the beta forum ;)
