To understand how to work with sound in JES, you must first understand the objects (or encodings) that represent sounds.
You can imagine that each sound is made up of a collection of samples, which is made up of sample 0, sample 1, sample 2, etc.
| Sounds |
Sounds are encodings of sounds, typically coming from a WAV file. |
| Samples |
Samples are collections of Sample objects, each indexed by a number, e.g. sample #0, sample #1, etc. samples[0] is the first Sample object, samples[1] is the second, etc. You can manipulate each Sample in the Samples like this: for s in samples: |
| Sample |
A sample is a value between -32768 and 32767 representing the voltage that a microphone would generate at a given instant when recording a sound. The length of the instant is typically either 1/44100 of a second (for CD-quality sound) or 1/22050 of a second (for good enough sound on most computers). A Sample object remembers what sound it came from, so if you change its value, it knows to go back and change the right sample in the sound. |
