Algorithm List
Mastering Tool Kit
This Kit is a compressor that splits sounds into different frequency band to unify their volumes. With this feature,
you can perform mastering at the optimized level when mixing down into an MD or a CD or when producing
your original audio CD using the CD-R disk.

Effect of “Detect Time” under Input
With ordinary compressors, a moment of delay occurs to suppress a level over instance after it has been detected.
With this algorithm, this problem is bypassed by using the input sound only for level detection and adding a
specified length of delay to the sound for processing and output. "Detect Time" under Input is the setting of the
delay time for this purpose. Note that supplying Detect Time causes time difference between input and output of
audio signals, requiring due considerations if used for operations other than mastering (ex. channel insertion).
Splitting into frequency bands
To split into high, middle and low frequency bands, Low Split
Point (LSP) and High Split Point (HSP) under Input are us^ to
specify frequencies.
