problem : The recording duration is 60 Seconds of dual channel audio , Sampling frequency is 44.1KHz, The quantized digits are 2 Bytes . If not compressed , Then the storage capacity is about MB？

The data amount formula of digital sound without compression is ： Bit rate （kb/s）X Transmission time （s）;

Bit rate = Sampling frequency （Hz）x Quantization Bits (bit) X Track number .

According to the title , Bit rate =44100Hz x 16bit x 2=1411200b/s=1411.2kb/s=176.4KB/s=0.1764 MB/s ;

Data volume =0.1764MB/s x60s=10.584MB

notes ：1 byte （Byte）= 8 The bit （bit）
