I am attempting to use MSRS software from NCH Swift Sound with a Mobile Pre in order to record two separate channels to a Dell Latitude D610 laptop and I have a speed issue.

I have the recording software set to make 15-minute files and the first file records fine, but when it creates the second file, the clock shows that the file is 8 minutes long and the recording is so slowed down as to be not usable. If you stop the recording and restart it, the first file will be 15 minutes and subsequent files will be 8 minutes.

I really like the software, but I need to be able to overcome this problem. I'm using the basic MSRS software because all I really need is two channels. Is my problem with the Mobile Pre, as I suspect or is there some other problem I can fix?

Double-check that the sample rate is set the same everywhere. It might be reading it at exactly half or double the sample rate.

Check with the software manufacturer. They are best suited to fix your issue. If they can't help, try M-Audio.

I appreciate your reply, but I have no idea what "check the sample rate" means. If you could elaborate, please.

I did post a request for help on NCH's website. Haven't heard from them yet. Perhaps they will have an answer.

Thanks.

(Oops, I thought the Mobile Pre was made by Metric Halo, I forgot it's actually made by M-Audio. Metric Halo's interfaces are called "Mobile I/O". In fact, doesn't the Mobile Pre come with Pro Tools software? It's great software, give it a try too.)

The sample rate is is an important concept to learn. It's not too complicated, and it will help you understand a lot about digital recording. Read these two articles and you'll be in great shape:

There was a great "Guide To Digital Audio" written by the folks at Apogee a few years ago, but they don't have it on their site anymore. So I've posted it here, it's essential reading:

Also check out the manuals for your M-Audio interface and the software. They likely describe where to set the sample rate.

Thanks much. I'll check all that out. Perhaps I'll find my answer. I appreciate your thorough response.
