[String] |
false | 6 | false | showcqt_bar_v |
Specify the sonogram gamma. Lower gamma makes the spectrum more contrast, higher gamma makes the spectrum having more range. Default value is 3. Acceptable range is [1, 7].

| Type | Required | Position | PipelineInput | Aliases |
|---|---|---|---|---|
[Double] |
false | 9 | false | showcqt_bar_t |
Specify the transform timeclamp. At low frequency, there is trade-off between accuracy in time domain and frequency domain. If timeclamp is lower, event in time domain is represented more accurately (such as fast bass drum), otherwise event in frequency domain is represented more accurately (such as bass guitar). Acceptable range is [0.002, 1]. Default value is 0.17.

[Double] |
false | 10 | false | showcqt_timeclamp |
Set attack time in seconds. The default is 0 (disabled). Otherwise, it limits future samples by applying asymmetric windowing in time domain, useful when low latency is required. Accepted range is [0, 1].

[String[]] |
false | 18 | false | showcqt_font |
Specify font file for use with freetype to draw the axis. If not specified, use embedded font. Note that drawing with font file or embedded font is not implemented with custom basefreq and endfreq, use axisfile option instead.
