Glossary

This page gives very brief explanations of these terms, with links to Wikipedia for much more comprehensive explanations.

We'll likely have a symbol for the wikipedia link. This page is optional and need not be in the manual, but I'm following up an idea on the Old Pages page.

• Amplitude:
• Cepstrum:
• dB: (decibels)
• FFT: (Fast Fourier Transform). A method for performing Fourier transforms quickly.
• FLAC:
• Filter: A sound effect that lets some frequencies through and suppresses others.
• Fourier Transform: A method for converting a waveform to a spectrum, and back.
• Frequency: The pitch of a sound. Measured in Hz, higher frequencies have higher pitch.
• Harmonics: Most sounds are made up of sounds of different frequencies. In musical sounds the component frequencies are simple multiples of each other, e.g. 100Hz, 200Hz, 300Hz, harmonics of the lowest frequency sound.
• High Pass Filter: A filter that lets high frequencies through.
• Hz (Hertz): Measures frequency as 'number of cycles per second'.
• LAME:
• Logarithmic:
• Low Passs Filter: A filter that lets low (bass) frequencies through.
• MIDI:
• MP2:
• MP3: A compressed audio format.
• Ogg Vorbis An Open Source compressed audio format.
• Spectrum: Presentation of a sound in terms of its component frequencies.
• WAV:
• Waveform:
• Wavelength:
