WAV file for cell phone ringtones

What is the WAV file format? The WAV format is a sound file format developed by Microsoft, also called a waveform sound file. It is the earliest digital audio format and is widely supported by Windows platforms and their applications. The WAV format supports many compression algorithms, multiple audio bits, sampling frequencies and channels. It uses a sampling frequency of 44.1kHz and 16 quantization bits. Therefore, the sound quality of WAV is almost the same as that of CD, but the WAV format requires too much storage space. It is very inconvenient to communicate and disseminate.
