Sample rate How many audio samples per second are analyzed. Higher values preserve more detail but can increase processing time. Hop length How far the analyzer moves between frames. Smaller values give finer time resolution, while larger values are faster and smoother. Smoothing frames How many neighboring frames vote on the final chord label. Higher values reduce flicker but can blur quick chord changes. No-chord threshold Minimum confidence needed before a frame is labeled as a chord instead of no chord. Raising it makes the detector more conservative. Min segment ms Shortest segment length to keep after merging. Very brief detections below this are folded into nearby segments.
