OCR: The Relation Between Audio Quality And Data Rate FIGURE 1 Quality Sample Rate Bits per Mono Data Rate {KHz) Sample Stereo (Uncompressed) Telephone 8 8 Mono 64Kb/sec (13 effective) AM Radio 11.025 8 Mono 88.2Kb/sec FM Radio 22.050 16 Stereo 705.6Kb/sec CD 44.1 16 Stereo 1411.2Kb/sec 1. Due to the logarithmic quantization curve, which uses smaller steps at quieter audio levels and larger steps at louder levels, the dynamic range of this algorithm is actually 13 bits rather than 8 bits.
