Soundspear – S1 v1.0.0 for WiN

The S1 uses a VCA detection circuit on a selected frequency range to detect signal peaks and increase the stereo signal spread accordingly. The image will become wider during high-energy transients to prevent phase drop.

You can select and mix various imaging algorithms, from Haas delay or classic mid-side correction to emulation of SRS transfer functions.

Characteristics

The input signal is first fed into a detection chain that responds to the average loudness of the song, where:

• Threshold controls the detection of the minimum peak,
• Speed controls the span of the moving average from the detection chain,
• Lowpass allows the detection input signal to be filtered using a biquad lowpass filter.
  

This detection circuit is used to dynamically adjust the stereo imaging of the sound:

• High Pass and Low Pass allow the stereo settings to be reduced to a single frequency band.
• Peak Gain is the stereo gain that will be applied when the detection circuit reaches its maximum value.
• Circuit allows the selection and combination of different imaging algorithms: binaural delay (Haas), head-related transfer functions (SRS) and mid-side gain (M/S).
  

The post-processing stage allows you to fine-tune the final render:

• Makeup applies negative makeup gain to compensate for induced stereo dispersion by reducing its average value,
• Comp reuses the input detection chain to apply VCA compression on the signal sides.
