Bitrate refers to how many bits per second the encoded audio data must be represented.<\/p>\n
lossy and lossless
\nFor “lossless audio” we usually mean, it generally refers to the 16-bit\/44.1kHz sample rate file format in the traditional CD format, and is called lossless compression because it includes the file format of 20Hz-22.05kHz. frequency response frequency that completely covers the audible range of the human ear.<\/p>\n
Where I have confusion here is the relationship between the channel and the sample rate? At first, the sample rate was assumed to be 44100. If two channels were used, the sample rate of each channel would be 22100. This is actually incorrect, the sample rate is the sample rate of each channel, not the sample rate of all channels.
\nTherefore, if the sample rate is 44100, then for two channels the number of samples collected should be 88200.<\/p>\n","protected":false},"excerpt":{"rendered":"
