About AHI
Definitions
Terms used in the following discussions may be unfamiliar. Some of the more important ones are defined below.
- Sample
- A sample is one binary number, representing the amplitude at a fixed point in time. A sample is often stored as an 8 bit signed integer, a 16 bit signed integer, a 32 bit floating point number etc. AHI supports only integers.
- Sample frame
- In mono environment, a sample frame is the same as a sample. In stereo environment, a sample frame is a tuple of two samples. The first member is for the left channel and the second member is for the right channel.
- Sound
Many sample frames stored in sequence as an array can be called a sound. A sound is, however, not limited to being formed by samples. It can also be parameters to an analog synth or a MIDI instrument, or be white noise. AHI supports only sounds formed by samples.
AHI Device
AHI device has two APIs: a library-like function interface (for low-level access) and device interface (for high-level access).
