| Interface | Description |
|---|---|
| AudioProcessor |
AudioProcessors are responsible for actual digital signal processing.
|
| Oscilloscope.OscilloscopeEventHandler |
| Class | Description |
|---|---|
| AudioDispatcher |
This class plays a file and sends float arrays to registered AudioProcessor
implementors.
|
| AudioEvent |
An audio event flows through the processing pipeline.
|
| AudioFile |
An audio file can be used to convert and read from.
|
| AudioPlayer |
This AudioProcessor can be used to sync events with sound.
|
| AutoCorrelation | |
| BitDepthProcessor |
Can be used to show the effect of bit depth modification in real-time.
|
| ConstantQ |
Implementation of the Constant Q Transform.

| DetermineDurationProcessor | |
| EnvelopeFollower |
An envelope follower follows the envelope of a signal.
|
| GainProcessor |
With the gain processor it is possible to adapt the volume of the sound.
|
| MultichannelToMono | |
| Oscilloscope |
The oscilloscope generates a float array with
array[i] an x coordinate in percentage
array[i+1] the value of the amplitude in audio buffer
array[i+2] another x coordinate in percentage
array[i+3] the next amplitude in the audio buffer
The implementation is based on the one by Dan Ellis found at http://www.ee.columbia.edu/~dpwe/resources/Processing/
|
| PipeDecoder |
Decode audio files to PCM, mono, 16bits per sample, at any sample rate using
an external program.
|
| SilenceDetector |
The continuing silence detector does not break the audio processing pipeline when silence is detected.
|
| SpectralPeakProcessor |
This class implements a spectral peak follower as described in Sethares et
al.
|
| SpectralPeakProcessor.SpectralPeak | |
| StopAudioProcessor |
Simply stops the audio processing
pipeline if the stop time is reached.
|
| WaveformSimilarityBasedOverlapAdd |
An overlap-add technique based on waveform similarity (WSOLA) for high
quality time-scale modification of speech
|
| WaveformSimilarityBasedOverlapAdd.Parameters |
An object to encapsulate some of the parameters for
WSOLA, together with a couple of practical helper functions.
|
| WaveformWriter |
Writes a WAV-file to disk.
|
| ZeroCrossingRateProcessor |
Calculates the zero crossing rate for a frame.
