Testing Methods
Pink Noise Frequency Test
Frequency analysis graph showing a pink noise signal input and how it is affected by pedal adjustments. Red line at -48 dB represents unaffected pink noise level.
Y-axis represents amplitude.
X-axis represents frequency.
Raw signal level is adjusted to a -20 dB total output.
Sine Wave Frequency Test
Frequency analysis graph showing a sine wave signal input and how it is affected by pedal adjustments. Sine wave is tuned to C4 (261.63 Hz).
Y-axis represents amplitude.
X-axis represents frequency.
Raw signal level is adjusted to a -20 dB total output.
Sine Wave Oscilloscope Test
Oscilloscope analysis graph showing a sine wave signal input and how it is affected by pedal adjustments. Sine wave is tuned to C4 (261.63 Hz).
Y-axis represents voltage.
X-axis represents time.
Raw signal level is adjusted to a -20 dB total output.
Level over Time Test
Level meter graph showing on audio sample clips over time and how it is affected by pedal adjustments. Red line at -20 dB represents unaffected audio sample level.
Y-axis represents amplitude.
X-axis represents time.
Grid resolution is set to 10ms.
