• WavReader.cpp - written in C++
• WavReaderQt.cpp - written in QT
• MetaReader.java - written in Java

![here] (/wav-sound-format.gif "WAV header")

• The "RIFF" chunk descriptor:

  1-4 "RIFF" Marks the file as a riff file. Characters are each 1 byte long

  5-8 File size (integer) Size of the overall file - 8 bytes, in bytes (32-bit integer).

  9-12 "WAVE" File Type Header. For our purposes, it always equals "WAVE".

• The "fmt" sub-chunk:

  13-16 "fmt " Format chunk marker. Includes trailing null

  17-20 16 Length of format data as listed above

  23-24 2 Number of Channels - 2 byte integer

  25-28 44100 Sample Rate - 32 byte integer. CSample Rate = Number of Samples per second, or Hertz.

  29-32 176400 (Sample Rate * BitsPerSample * Channels) / 8. Byte rate

  33-34 4 (BitsPerSample * Channels) / 8.1 - 8 bit mono2 - 8 bit stereo/16 bit mono4 - 16 bit stereo

  35-36 16 Bits per sample

• The "data" sub-chunk:

  37-40 "data" Marks the beginning of the data section.

  41-44 File size (data) Size of the data section.
