The data in WAV files are stored in chunks that contain a four-character tag and the number of bytes. The WAV format is an application of the Resource Interchange File Format (RIFF), and use the same method for storing data. Read More: Input Formats - list of supported WAV Codecs. Read More: How to setup output WAV codec. To WAV Converter and To Audio Converter support output WAV codecs from the list below:Ĭodecs, such as G.711, ADPCM, and GSM 6.10 can provide a good compression and satisfactory quality for the Voice Audio. The number of potentially supported WAV codecs is limited by 65535 (32767) by the WAV format (see the formatType field in the structures below). WAV files also are capable of storing the audio processed with different compression audio codecs. Therefore, in such cases, the WAV files are not as popular as their smaller, more portable counterparts. Sending and downloading such WAV files also takes much more time and space. The WAV files with uncompressed audio are taking more space than MP3, MP4, or FLAC files. The standard file extension for WAV format, accepted by audio applications, is. WAV files usually contain uncompressed audio encoded with Pulse-Code Modulation ( PCM) audio codecs. It is one of the most common audio formats and was created by Microsoft in collaboration with IBM. WAV stands for Waveform Audio File Format.
