An audio frame is the group of audio samples for an instance of time that come from one or more audio channels. The most common values for the sampling rate is the aforementioned 8kHz (most common for telephone communications), …
Difference between frame and sample in waveform - Sound ...

In that context a frame is the quantity of audio samples taken during a video frame interval. If there are 30 video frames per second and 48000 audio samples per second, you could say that there are 48000 / 30 = 1600 samples per frame, or that an "audio frame" contains 1600 samples, but there literally is no audio frame, it's just a convention for talking about audio with …

Each audio frame is a data record that contains the samples for all of the channels available in an audio signal. The size of an audio frame is calculated by multiplying the sample size in bytes by the number of channels, so a single frame of stereo …

the audio has a framerate/samplerate of 44100 per sec or hz and total frames are 9745238 and the duration of the audio is 220 secs by the file properties whereas it should be 220.9804535147392 secs and has 2 channels.

if you view the matrix using the scipy library then instead of _ there will be numbers whose value will be according to decoded string and to put the statement in another way we can say that each element in the matrix is a sample. so there are total 12 samples in the audio and if we suppose duration of the song to be, 1 sec then the frame_rate will be 4hz and sample_rate …

Audio for film and TV broadcast should always be recorded at 48 kHz or one of its variants, 48.048 kHz and 47.952 kHz. If you have been instructed to shoot at 48.048 kHz or 47.952 kHz, always select the ‘fake’ stamped sample rates of 48.048F or 47.952F respectively unless otherwise instructed by pre-production.

audio - What is a "sample" in MP3? - Stack Overflow
https://stackoverflow.com/questions/11253233/what-is-a-sample-in-mp3
Each MP3 frame contains 2 granules of 576 samples (that correspond to 576 new and 576 old PCM samples). This means 576 samples per channel, or 1152 samples total. Each frame therefore corresponds to 1152 new PCM samples per channel, so 2304 samples. Each granule contains huffman bits for both channels, scale factors for both channels.

GetInputChannelCount returns the input channel count (samples-per-frame) for this APO. IAudioProcessingObject::GetLatency The GetLatency method returns the latency for this APO. Latency is the amount of time it takes a frame to traverse the processing pass of an APO. IAudioProcessingObject::GetRegistrationProperties

When you configure a block to perform frame-based processing, the block interprets an M-by-1 vector as a single-channel signal containing M samples per frame. Similarly, the block interprets an M-by-N matrix as a multichannel signal with N independent channels and M samples per channel. For example, in frame-based processing, blocks interpret the following sequence of 3 …
