What is the difference between frame and sample?
A sample is the smallest usable quantum of digital audio. The term frame isn't formally defined in pure audio terms, but is often used in relation to video that may accompany an audio track. In that context a frame is the quantity of audio samples taken during a video frame interval.
What is a frame in a WAV file?
A frame consists of samples. There is one sample per channel, per frame. Every wav file has a sample width, or, the number of bytes per sample. Typically this is either 1 or 2 bytes. The wav module supplies more convenient access to this data.
How many audio samples are in a frame?
A frame consists of exactly one sample per channel. If there is only one channel (Mono sound) a frame is simply a single sample. If the sound is stereo, each frame consists of two samples, etc. is 8 bits, and we're handling mono sound, the frame size is one byte.
What is audio framing?
Each audio frame is a data record that contains the samples for all of the channels available in an audio signal.
