Frequently Asked Questions

The presets are far too loud! What's going on?

This is the most common question! The presets included with the DSM V2 represent an interesting set of Threshold Curves which have been captured from commercially successful productions. However, the first thing you'll have to do is adjust the overall Threshold level to fit the track you're processing. Secondly, as the presets are all at maximum Ratio and maximum Makeup Gain, you'll also typically reduce the Ratio and Gain to more moderate settings.

Does the DSM V2 do some expansion as well as compression?

No. The DSM V2 is purely a compressor and limiter.

Is the DSM V2 deterministic? It has so many frequency bands, surely it can't be deterministic.

The DSM V2 is deterministic. It runs a mathematical algorithm the same way every time.

Are DSM presets compatible with the DSM V2?

Sorry, no. However, as the DSM V2 is a separate plugin from the DSM, you can continue to use the DSM in your existing sessions.

Is the DSM a conventional multiband compressor?

No. The crucial difference with the DSM is that it uses the underlying frequency content of the program itself as the basis for compression. This means that it is able to compress much more sympathetically (and tackle more difficult and sensitive program) whilst retaining the essential character of the music. Other innovative aspects such as the ability to capture programme information over time and frequency, which can be applied both to its own compression character, and to other tracks, put the DSM into an entirely new class of processing.

Can the DSM be used to maximise program volume?

Yes. The limiter function will prevent peak over loads, so you can increase the gain to drive higher levels. The included set-ups called 'louder x' illustrate this. You can capture the spectrum of your programme at it's loudest, let the DSM raise levels to match that sound, then increase the gain or threshold and allow the limiter to avoid over loads.

Can I use the DSM after my usual buss processing to make the program even louder?

This is possible. Since the DSM acts on the frequency response as well as level in some cases it can make heavily compressed program sound even louder. The method is to capture the sound where it is loudest and let the DSM apply this to the whole track. However, care should be taken to avoid increasing distortion from the previous buss processing - in some cases the DSM may produce better results alone.

How do I apply the sound of one track or instrument to another?

You simply capture the spectrum of the track with the DSM, then play another track through it keeping the same settings. If you do not want compression, you can hit the freeze gains function and the DSM will apply only the frequency profile to your track - like a complex EQ curve.

How do I process and de-ess vocals?

You press the capture function during a period where the vocals sound good, then release it and let the DSM apply this to the rest of the track. You can then adjust timing and ratio to suit the track and if necessary increase the threshold so that the changes only affect higher levels. It works particularly well because the sound it applies is actually derived from the vocals themselves - it's not just blanket EQ or HF reduction which removes vocal character in conventional processes.

Can I use it to fix up mic placement wander on film and video post production?

Yes. The dialogue enhance settings illustrate this kind of use. The procedure is similar to vocal processing, but using faster timing settings. You can capture when the dialogue at it's clearest and let the DSM raise the whole dialogue track to this level, with this overall response. Not only will the DSM correct for level, it will also correct for frequency response changes when the the subject wanders from the microphone.

The Parametric Threshold section looks like a set of EQs - is it?

No. It does not EQ the program directly. These are used to modify the captured spectrum (or produce one from scratch) to allow you to change the character of the sound. The EQ style controls are used because they are familiar.

When I change the Parametric Threshold response manually or load new settings I don't always hear the results immediately. Why is this ?

Changes to the Parametric Threshold response are applied immediately, but due to the timing of the compressors it takes time for the levels in the bands to adjust from previous values. This is also the case when changing between settings. A short wait is required to hear the full effect of the settings.

Why doesn't the CPU load go down when I switch off the Parametric Threshold sections?

The Parametric Threshold sections simply modify the threshold curve, so they do not create any extra processor load. The ‘In’ buttons are provided to allow easy before and after comparisons.

How do I use the Capture button?

Press and immediately release to capture a transient point in the programme. Press and HOLD for as long as you want to capture the average spectrum of the programme.
