VMG-01 Sample Delay

Audio examples

The VMG-01 is a sample-accurate delay and delay measuring device. It can be used to induce delays as short as one sample and as long as 99,999 samples to any stereo signal flow while operating in true stereo. It also features a test signal output and a measuring input to test devices for their inherent latency.

Using these features you can use it to effectively compensate for latencies in your signal flow while mixing. The sample accurate delay is also very useful for precise comb filtering and haas effect type stereo imaging effects.

Product details

Usage Examples

Latency Compensation

Many audio devices induce a short delay into the signal flow to better handle for example transients and fourier transforms. When such signals are mixed back into a mix of, e.g., a drum set, timing and phasing issues arise.

As the induced delay is inherent to the device the only chance to get the tracks back in sync is to induce the same delay into the signal flow of the other instruments. Of course, the original devices latency needs to be known as accurately as possible. This is where the VMG-01 comes in.

By using the VMG-01 test signal and measuring input, you can measure the latency of your devices signal flow and induce the same latency into the other channels.

Fine Grained Comb Filtering and Doubling

Due to the fine resolution of the delay parameter it is possible to apply very specific comb filtering and doubling effects using the VMG-01.

For comb filtering effects, split the signal of any mix channel and apply a VMG-01 to the split signal. Now you can fine-tune the delay between original and copy causing comb filtering effects from very subtle to strong coloration.

For doubling and using the Haas Effect to position and widen the stereo image of a signal, split the signal of a mono channel and apply a VMG-01 to the split signal. Pan the original signal hard left and the split signal hard right. When you raise the delay value to about 440 at 44,100 Hz sampling rate you start hearing the Haas Effect and the signal will both sound wider and start to move to the left speaker the more you raise the delay. Compensate the positioning using the volume fader of the original and delayed signal as a balance control.
