Optional options: Partial<BiquadFilterOptions>Readonly QThe Q factor of the filter. For lowpass and highpass filters the Q value is interpreted to be in dB. For these filters the nominal range is [−𝑄𝑙𝑖𝑚,𝑄𝑙𝑖𝑚] where 𝑄𝑙𝑖𝑚 is the largest value for which 10𝑄/20 does not overflow. This is approximately 770.63678. For the bandpass, notch, allpass, and peaking filters, this value is a linear value. The value is related to the bandwidth of the filter and hence should be a positive value. The nominal range is [0,3.4028235𝑒38], the upper limit being the most-positive-single-float. This is not used for the lowshelf and highshelf filters.
Readonly contextThe context belonging to the node.
Set this debug flag to log all events that happen in this class.
Readonly detuneA detune value, in cents, for the frequency.
Readonly frequencyThe frequency of the filter
Readonly gainThe gain of the filter. Its value is in dB units. The gain is only used for lowshelf, highshelf, and peaking filters.
Readonly inputThe input node or nodes. If the object is a source, it does not have any input and this.input is undefined.
Readonly nameThe name of the class
Readonly outputThe output nodes. If the object is a sink, it does not have any output and this.output is undefined.
Static versionThe version number semver
The number of seconds of 1 processing block (128 samples)
console.log(Tone.Destination.blockTime);
channelCount is the number of channels used when up-mixing and down-mixing connections to any inputs to the node. The default value is 2 except for specific nodes where its value is specially determined.
channelCountMode determines how channels will be counted when up-mixing and down-mixing connections to any inputs to the node. The default value is "max". This attribute has no effect for nodes with no inputs.
channelInterpretation determines how individual channels will be treated when up-mixing and down-mixing connections to any inputs to the node. The default value is "speakers".
Indicates if the instance was disposed. 'Disposing' an instance means that all of the Web Audio nodes that were created for the instance are disconnected and freed for garbage collection.
The number of inputs feeding into the AudioNode. For source nodes, this will be 0.
const node = new Tone.Gain();
console.log(node.numberOfInputs);
The number of outputs of the AudioNode.
const node = new Tone.Gain();
console.log(node.numberOfOutputs);
The duration in seconds of one sample.
The type of this BiquadFilterNode. For a complete list of types and their attributes, see the Web Audio API
Connect the output of this node to the rest of the nodes in series.
Rest ...nodes: InputNode[]const player = new Tone.Player("https://tonejs.github.io/audio/drum-samples/handdrum-loop.mp3");

const filter = new Tone.AutoFilter(4).start();
const distortion = new Tone.Distortion(0.5);
// connect the player to the filter, distortion and then to the master output

Get the object's attributes.
const osc = new Tone.Oscillator();
console.log(osc.get());
Set multiple properties at once with an object.
const filter = new Tone.Filter().toDestination();
// set values using an object
filter.set({
frequency: "C6",
type: "highpass"
});
const player = new Tone.Player("https://tonejs.github.io/audio/berklee/Analogsynth_octaves_highmid.mp3").connect(filter);
player.autostart = true;
Convert the incoming time to seconds. This is calculated against the current TransportClass bpm
const gain = new Tone.Gain();
setInterval(() => console.log(gain.toSeconds("4n")), 100);
// ramp the tempo to 60 bpm over 30 seconds
Tone.getTransport().bpm.rampTo(60, 30);
Static get
Thin wrapper around the native Web Audio BiquadFilterNode. BiquadFilter is similar to Filter but doesn't have the option to set the "rolloff" value.
