Calculations

1. Playback duration = 11 s
   1. Formula 1: data[chunkSize] / avgBytesPerSec
      352000 / 32000
   2. Formula 2: data[chunkSize] * 8 / (samplesPerSec * bitsPerSample * channels)
      352000 * 8 / (16000 * 16 * 1)
2. File size = 352078 B
   1. Formula 1: RIFF Chunk Size + RIFF Header Signature(field size) + RIFF Chunk Size(field size)
      352070 + 4 + 4

Notes

Format settings Little-Endian: least significant byte stored first. Big-Endian: most significant byte stored first.
