Slow Record Speed When Converting To Digital From Tape

[Bob 5880]

When converting from tape to a digital format, the recording is done a about half speed.

In other words a 30 minute playback from tape produces a 15 minute recording.

Do you have Creator NXT? How are you capturing the audio? Are you using a capture device or do you have the tape deck plugged directly into your audio card? Tell us about how you are going about it?

I'm using Creastor NXT and recording from tape to a sound card. The problem can be observed without any input. Just start the record process. The time display of the reocding proccess will be about half that of the elapsed time.

There are at least 4 ways you can capture audio in Creator NXT. It would help to tell us exactly which one you are using? You can use 1) Digitize LP and Tapes, 2) Capture Audio from Sound Card, and there are captures in "Create Music Discs Projects" and "Edit Audio ". There are probably more but you get the idea.

 

Did you play the capture? Is it twice as fast as it is supposed to be or are you just relying on the numbers on the time scale (which few use).

 

We need the information so we can try to duplicate what you see. If you respond, I will dig out my old tape player and try it.

I'm using Windows 7. No other applications are running. The system manager indicates memory usage as less the 5% prior to trying to record. When real audio is played back, it plays back at twice speed (chipmonk). This is in agreement with the numbers about record length.The orginal problem was noted when useing 1) Digitize LP and Tapes. I've since tried using 2) Capture Audio from Sound Card and 3) Create Music Disks. The results are the same. I tried changing the sample rate to 8 bits and got 2 successful recordings. Tried a few hours later for a third recording and got the chipmonks.

Or chipmunks (non-religious chipmonks).

What format are you capturing? I used wav and the standard presets and got a 30 second file for a 30 second capture. What is the bit rate you are using?

 

You said you changed the sample rate to 8 bit. What did you change it from?

 

Do you have an m-audio card?

[Bob 5880]

Formats as follows:

.wav - stereo - Encoder PCM - Format 44.100 - Bits per Sample 8 or 16

This morning, both sample rates worked. The recordings went OK.

A simple way to tell if it's going to work is too look at the time remaing on the hard drive.

When the record rate is wrong I have about 600 hours, when the record rate is OK I have about 300 hours.

What;s strange ! Did you reboot overnight? Did you do any computer maintenance - defrag, get rid of junk files?

 

Let us know if the problem comes back.

[Bob 5880]

The problem seems to have gone away. I've rebooted twice today and it's still woriking OK. When it first started I tried rebooting a couple of times and was still there. No deliberate changes where made to the system. Updates are set to notify first. Ill just keep an eye on it. Thanks for trying to help.
