Audiocomplib v0.1.3

What's New in Version 0.1.3

1. Fixed Soft Knee Implementation:

   • The soft knee implementation was incorrect in previous versions. This has been fixed to ensure a smooth quadratic transition within the knee region.
   • The new implementation uses the equation:

     y = x + ((1 / R - 1) * (x - T + W/2)^2) / (2 * W)
     

     where:
     • x is the input level (in dB),
     • y is the output level (in dB),
     • R is the compression ratio,
     • T is the threshold (in dB),
     • W is the knee width (in dB).
   • This ensures a seamless transition between the uncompressed and compressed regions.

2. Moved Target Gain Reduction Calculation to target_gain_reduction Public Method:

   • The calculation of the target gain reduction has been moved to the target_gain_reduction public method.
   • This makes the method more accessible and reusable for users who want to compute gain reduction without processing the entire signal.

3. Added Example for Computing and Drawing Transfer Curves:

   • A new example has been added to demonstrate how to compute and draw the transfer curves of AudioCompressor and PeakLimiter using the target_gain_reduction method.
   • The example uses matplotlib to visualize the input-output relationship in both linear and dB scales.
