Subject:Echo when recording

When I record into SF, the sound has some latency. Is there a filter to get rid of it? It sounds as if I'm in a hollow tube.
Thanks,
Richard

You need to provide way more info for any sensible answer.
What system specs do you have ( fill it into your profile and also post it here). ?
Very importantly, what sound card and "audio device" (in SF) drivers are you using.?
What version of SF?

I’m running a 2 core quad Q6600 2.4GHz CPU; 3 GB RAM; plenty of hard drive space (3 500 GBs); graphics board is Gigabyte GeForce 8600GT 256MB; motherboard is a Gigabyte GA-P35-DS4 LGA 775 Intel P35. The sound function is part of the motherboard; the mic is a Rode Podcster USB.

For the mic, I’m using the Rode device driver. What others are there?
Thanks,
Richard

Richard,

I have an almost identical system as yours--the same motherboard and processor. I found the onboard sound completely unusable. I could not record anything usable from the mic input and the playback always had lots of chirping noises, especially under high disk activity. I'd suggest trying an add-on soundcard and see if your recording and playback improve. Right now, I'm using a very old soundblaster that is way better than the onboard chip. Hope this helps.

I've got a P35 DS3R - and actually found the on-board stuff to be pretty good, all things considered. Yes, for my work I use a 'proper' sound card, but I still wouldn't dismiss the realtek onboard HD, once you work out how to set it up.
Firstly, there are things in the realtek control panel worth findgin, such as auto removal of dc offset, then there is the mic boost level which helps. The output side is even better.
If you're using the onboard for playback, check out "asio4all" straight away - it'll open up the output options and reduce latency from ~46ms down to ~10ms.

As for the rode, do you still get the echo, if you mute your speakers (as a test)? Wondering if you're getting an audio feedback loop of some sort.

No intent to hijack this thread, but how do you access the settings you mentioned? I've installed the latest driver package and can't seem to find them. Thanks.

Based on Vista:

1) Right click on realtek icon on taskbar.(and choose sound manager)
Choose microphone tab, and alongside recording volume fader, you'll see a boost icon that you can use. You can also configure noise supression, acoustic echo cancellation, beam forming, default format (cd vs dvd quality)
Also, look in the top right for advanced settings.

2) Right click, but this time choose Audio devices.
On recording tab, find realtek high definition audio working. Under properties, look at enhancements - and you'll also find DC offset cancellation.

I'm using XP and none of the options you list are available. E.g., when I choose the micrphone tab, there is no volume slider. The volume slider is shown under the mixer tab, but there is no boost icon. I also note that the volume controls are grayed out, suggesting I might have other problems--perhaps since I also have another sound card installed.

Here's a screen-grab:

But that's why I put based on Vista - in case there was more functionality within Vista. As for controls being greyed out. Don't know - I run multiple soundcards, and always have options galore, not greyed out.

Hope that somehow helps

I got rid of the echo, I think, by going to the gigabyte interface and using the Audio I/O tab. Ihd 5 speakers selected and changed it to 2 speakers. That seems to have gotten rid of the echo. On the Microphone tab, I selected Acoustic Echo Cancellation. I'm not sure which, if either, fixed the problem, but I don't have the guts to find out. I guess if it not broken, don't fix it.

If you're only running a stereo config, then switching to 2channel is better anyway, because any surround material can be automatically downcoverted for you, instead of you actually missing the program material.
The A.Echo.Cancellation will likely have sorted it, but if you're working now, then that's all that matters
