We give you some examples, but you can choose another one. Please, be aware that depending on the audio system and/or device, not all the sampling frequencies are available. Anyway, you can get close to your desired effective sample rate by combining this parameter with the oversampling factor (Basic tab). If you are using JACK, you cannot modify this field, but you can change it externally (in the JACK server configuration). 1 2 2 3 GTK_SHRINK | GTK_FILL 0 False True Audio input settings.

Adjustments 1 False tab True 10 4 3 10 10 True True This is the most recent amount of data considered for tuning. The longer it is, the more accuracy you can obtain, but also the dynamic response gets lower, because you are considering older parts of the signal. Also, if you raise this parameter, the computational cost increases. This value, in samples (depending on the effective sample rate), must be greater or equal to the FFT buffer size. 1 0.32000000000000001 0 15 0.01 0 0 3 1 2 2 3 True The FFT buffer gives Lingot a first look to the spectrum. Higher values can help Lingot to hook up the correct peak, but it's also computationally more expensive. Don't use high values here unless you have an equally high effective sample rate. 256 512 1024 2048 4096 1 2 1 2 True 4 True Hardware sampling frequency 8000 True / 1 2 True True True Oversampling factor 1 1 1 120 1 10 0 2 3 True Effective sampling frequency. The lower this parameter is, the more accurate the FFT will be, and hence the better is the hooking up to the correct peak.
