Glossary¶
- Beamforming¶
A related, but separate area of research that tries to estimate isolate sources using multiple recordings of an auditory scene from different angles and locations.
- DFT¶
“Discrete Fourier Transform”
- Downsample¶
Resample an audio signal such that the sample rate is lower than it originally was.
- Mono¶
An audio signal is monophonic, or mono, if it only has one channel of audio data.
- Monophonic¶
An audio signal is monophonic, or mono, if it only has one channel of audio data.
- Sample¶
A single measurement from a continuous-time signal that becomes a discrete-time signal.
- Sample Rate¶
The number of digital samples that occur per second.
- Short-time Fourier Transform (STFT)¶
A time-frequency representation that has phase and magnitude.
- Stereo¶
An audio signal is stereophonic, or stereo, if it has exactly two channels of audio data.
- Stereophonic¶
An audio signal is stereophonic, or stereo, if it has exactly two channels of audio data.
- STFT¶
“Short-time Fourier Transform”
- TF¶
“Time-Frequency”
- TF bin¶
A single value in a Time-Frequency matrix.
- TF Representation¶
A general term for any 2D representation of audio that represents time along one axis and frequency (or pitch) along the other. This might be an STFT, a spectrogram, CQT, LogMel-Spectrogram, etc.
- Upsample¶
Resample an audio signal such that the sample rate is higher than it originally was.
- Waveform¶
A
