MP3 - Audio File Format
https://docs.fileformat.com/audio/mp3/
An MP3 file consists of MP3 frames where each frame consists of a header and a data block. The frames are not independent and cannot usually be extracted at arbitrary frame boundaries. The data blocks of file contains information about the audio in terms of frequencies and amplitudes.
MP3 File Format Specification - mpgedit
http://mpgedit.org/mpgedit/mpeg%5Fformat/MP3Format.html
An MPEG audio file is built up from smaller parts called frames. Generally, frames are independent items. Each frame has its own header and audio informations. As there is no file header, you can cut any part of MPEG file and play it correctly (this should be done on frame boundaries but most applications will handle incorrect headers).
mp3Frame - ID3.org
FrameSize = 144 * BitRate / SampleRate when the padding bit is cleared and FrameSize = (144 * BitRate / SampleRate) + 1 when the padding bit is set. The !frameSize is of course an integer. If for an example BitRate=128000, SampleRate=44100 and the padding bit is cleared, then the FrameSize = 144 * 128000 / 44100 = 417.
MP3 File Structure Description - Multiweb.cz
http://www.multiweb.cz/twoinches/MP3inside.htm
MP3 file is divided into a small blocks - frames. Each frame has constant time length 0.026 sec. But size of one frame (in Bytes) varies according to bitrate. Eg. for 128kbps it is (normally) 417 Bytes and for 192kbps 626 Bytes. The first 4 Bytes of each frame is …
java - How to get audio data from a MP3? - Stack Overflow
https://stackoverflow.com/questions/938304/how-to-get-audio-data-from-a-mp3
When using mp3 files I'm not sure how to handle data (the data I'm interested in are the the audio bytes, the ones that represent what we hear). If I'm using a wav file I know I have a 44 bytes header and then the data. When it comes to an mp3, I've read that they are composed by frames, each frame containing a header and audio data.
MP3' Tech - Frame header
http://www.mp3-tech.org/programmer/frame_header.html
The frame header itself is 32 bits (4 bytes) length. The first twelve bits (or first eleven bits in the case of the MPEG 2.5 extension) of a frame header are always set to 1 and are called "frame sync". Frames may also feature an optional CRC checksum. It is 16 bits long and, if it exists, immediately follows the frame header. After the CRC comes the audio data.
MP3 - Hydrogenaudio Knowledgebase
https://wiki.hydrogenaudio.org/index.php?title=Mp3
The MP3 file has a standard format which is a frame consisting of 384, 576, or 1152 samples (depends on MPEG version and layer) and all the frames have associated header information (32 bits) and side information (9, 17, or 32 bytes, depending on MPEG version and stereo/mono).
A More Loss-Tolerant RTP Payload Format for MP3 Audio
http://www.live555.com/rtp-mp3/
Here is the original MP3 data: 24 kbps version (MPEG 2 layer III; encoded at 16000 Hz; 108-byte frames; 36 ms per frame) 128 kbps version (MPEG 1 layer III; encoded at 44100 Hz; 417 or 418-byte frames; ~26 ms per frame) Frame loss The following files show the effect of random (Poisson) 10% frame loss applied to this same data. Note the audio artifacts. These are a …
Audio graphs - UWP applications | Microsoft Docs
https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/audio-graphs
An audio frame output node allows you to receive and process audio data output from the audio graph with custom code that you create. An example scenario for this is performing signal analysis on the audio output. Create an AudioFrameOutputNode by calling CreateFrameOutputNode. AudioFrameOutputNode frameOutputNode;
