For starters, it uses many more bands, resulting in far greater detail in the midrange and top end. Most unusually, before you start processing with DSM, you need to first analyse a 'source' signal, which the software will then use as a virtual 'reference', pushing the processed signal closer towards its dynamic and tonal qualities.

Since DSM works with dynamic as well as spectral information, there's plenty of scope for its application. The basic workflow involves capturing the profile of a desirable signal, then applying that profile to your target audio. Often, this will be a case of capturing the best- sounding part of the signal in a section of a track and using it to reshape the rest of the same track.

For example, an over-sibilant vocal can easily be treated by holding down the Capture button during a passage where no sibilance occurs, then when the vocal track is processed by DSM, the sibilance is suppressed throughout the entire performance.

In another example, you could capture one of the the bright, loud transients from a drum buss and use it to increase the overall level and brightness of the whole drum mix. Or perhaps you'd like to apply the sound of one instrument or even an entire mix to another - DSM's got you covered.

Does it really work?

Even at extreme settings, DSM doesn't suffer from the typical distortion or choking artefacts of compression (although with careful settings, you can make it produce creative pumping effects). Nor does it suffer from the typical crossover frequency problems associated with multiband compression. Rather, it generates its own particular artefacts if abused, resulting in a grainy, distorted sound or just an unusual frequency curve when the captured profile is inappropriate for the destination track.

However, it's difficult to make it sound bad under normal operation, and fixing poor sounds is made easy by the low- and high-frequency Timing Profile faders and the Parametric Threshold controls (like an EQ applied to the capture).

In conclusion, Dynamic Spectrum Mapper is genuinely capable of dramatically improving almost any audio material, usually within a few minutes at most. It works in sympathy with the original signal to prevent unusual artefacts and sounds good enough to be used for both mixing and mastering. It's a forward-thinking processor that produces amazing results, often replacing whole chains of effects and saving hours of tweaking.
