Question
I am checking a 2-channel, 16-bit, 44,1kHZ WAV file and get this as response:
{
"tagTypes": [
"exif",
"ID3v2.3"
],
"trackInfo": [],
"container": "WAVE",
"codec": "PCM",
"bitsPerSample": 16,
"sampleRate": 44100,
"numberOfChannels": 2,
"bitrate": 352800,
"lossless": true,
"numberOfSamples": 137095,
"duration": 3.108730158730159
}
The bitrate has me confused. I was expecting 1411200.
This answer is consistent for multiple WAV files.
What am I missing here?
Looking at the source-code it seems to be calculated by blockAlign * 8 * sampleRate, which would imply a block-align or 1. However, for a stereo 16-bit file this block-align should be 4.
