Use the Use mono impulse on mono input button if you don't want mono input signals to be converted to
stereo (this happens if the impulse file is stereo). Doing this halves the Convolutor's CPU usage. Clicking
the Mono Button has no effect until the Transport is restarted.
the Mono Button has no effect until the Transport is restarted.
kHz should be set to the samplerate of the impulse response file (MultitrackStudio can't detect it
automatically). Impulse response file are typically sampled at 44.1 kHz.
Volume controls the output level. This control will be updated automatically when a new file is loaded using
the Load button.
Use the Delay knob to add a delay to the processed signal. This can be useful for reverb applications.
The Mix with input button adds the input signal to the output of the effect.
Convolutor is 'zero latency', so it doesn't add a delay to the signal.
Using the Convolutor 'live'
The Convolutor can be used 'live' (either in a recording MIDI track with a software instrument, or in a
recording audio track using the Soft Monitoring feature). The following remarks apply in this situation:
l
The Convolutor is significantly less efficient. Mouse movements can become real slow on older
computers. It's recommended to use the Bypass button when loading an impulse file, so the Length
Limit control can be lowered in order to reduce CPU usage.
l
A small latency may occur if the ASIO buffer size isn't a power of two (256, 512, 1024 etc.).
Recording impulse response files
You can create your own impulse response files using Impulse.gjm which is in the folder where
MultitrackStudio is installed (usually C:\Program Files\MtStudio). This file contains a single impulse at about
50 ms from the start of the file (to make sure that is gets at the output of your sound device, even if it has
some kind of fade-in algorithm to avoid clicks).
Recording an impulse response file is easy:
1. Connect your sound device's output to the input of the piece of gear you want to use.
2. Connect the piece of gear's output to your sound device's input.
3. Load 'Impulse.gjm' in a track. The track should be in playback mode.
4. Set up another track that will record the impulse response file.
5. Record a few seconds and then use the recording track's Editor to check the level of the recording: it
should be just below full scale. If necessary record it again.
6. Export the piece of the recording that contains the impulse response. The starting point is just before
the pulse appears in Impulse.gjm. The ending point is where the impulse response has faded (look at
editor and/or listen). Impulse responses typically have a length of 1..4 seconds for reverbs. For other
things 0.5 seconds usually will do.
If your sound device makes clicking sounds when you start the Transport you should edit Impulse.gjm so
that the impulse is at about 1 second from the start.
7.6 Deesser
The Deesser effect reduces 'S' sounds in vocals in a very unobtrusive manner.
Deesser window
De-Es controls the amount of attenuation applied to 'S' sounds. Applying too much attenuation will result in
