Audio Frame - an overview | ScienceDirect Topics

    https://www.sciencedirect.com/topics/engineering/audio-frame
    In data format terms, the digital audio signal is divided into frames. Each digital audio frame contains a complete digital audio sample for both left and right channel. If 48 kHz sampling is used, it is obvious that 48 000 frames pass over the link in every second, leading to a final baud rate of 3.072 Mbit/s.

    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 16-bit audio is 4 bytes long and a single frame of 5.1 floating-point audio is 24 (4 bytes per sample multiplied by 6 channels).

Difference between frame and sample in waveform - Sound ...

    https://sound.stackexchange.com/questions/41567/difference-between-frame-and-sample-in-waveform
    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 …

technical - How many samples are in a frame? - Sound ...

    https://sound.stackexchange.com/questions/5022/how-many-samples-are-in-a-frame
    each frame audio depends on a video if a video is of 96 / 24 then it would be 96000 / 24 you will get a frame's sample so it would be 4000 samples per frame and if it is 48/24 it would be 2000 samples per frame :D.

python - What does a audio frame contain? - Stack Overflow

    https://stackoverflow.com/questions/3957025/what-does-a-audio-frame-contain
    An audio frame, or sample, contains amplitude (loudness) information at that particular point in time. To produce sound, tens of thousands of frames are played in sequence to produce frequencies. In the case of CD quality audio or uncompressed wave audio, there are around 44,100 frames/samples per second.

Sample Rate and Frame Rate Settings for Production …

    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.

    The most common audio sample rate you’ll see is 44.1 kHz, or 44,100 samples per second. This is the standard for most consumer audio, used for formats like CDs. This is not an arbitrary number. Humans can hear frequencies between 20 Hz and 20 kHz.

    XXX frames discarded" In my case, my problem was that I went out of memory or something like that. The warning appeared when I exceed preparing/loading my videos (VideoPlayer.prepare). I prepared a total of 52 videos with 52 video players. The first half runs ok, but the other half got this warning and the audio never sound.
