Waveform
A waveform is a representation of how a time-varying signal changes over time, often showing an audio signal’s amplitude.
Learn Haskell by Example
A waveform is the shape of a signal as it varies over time, especially the periodic shape used to define a tone.
- How it is used
- Generates periodic signals for tones in a digital music synthesizer.
- How deep it goes
- Defines waveform functions and connects periodic sampling to frequency, stopping before later volume modulation.
- Examples
- Uses sine, square, sawtooth, and triangle functions to create a 220-Hz exported audio file.
- What you can do after
- Build it from scratch in Haskell by defining waveforms and producing sampled tones.
Transformers in Action
A waveform is a representation of a time-varying signal, such as an audio signal.
- How it is used
- Represents sampled audio before transforming it into features suitable for multimodal model inference.
- How deep it goes
- Defines amplitude samples and traces conversion through spectrograms, but stops short of detailing encoder internals.
- Examples
- Demonstrates video extraction, 16 kHz mono WAV conversion, mel inspection, music analysis, and speech transcription.
- What you can do after
- Operate/configure an audio pipeline that extracts, validates, visualizes, and queries waveform data.
