A headphone output would be nice, as would balanced output. WebNov 3, 2024 · Whenever you see a zigzag like this that settles below 90 dB, it indicates that the DAC is simply throwing away extra bits in our 24 bit samples and is just using 16 bits. This type of conversion is bad as it generates steps in response that result in fair bit of distortion. Proper conversion with dither (noise addition) needs to be performed. WebAudio bit depth. An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample. ipla sharepoint
