Audio

Different audio files keep different types of sounds. Some are used for music and general audio, whilst others can be used in speech recognition and research. Different audio file types and extensions come with different characteristics. Each can hold a different number of audio channels, support fixed or variable bitrates, or can include other metadata.

Here you will find both common and uncommon audio file types which you can download in different audio lengths and file sizes. Click on the respective download button below and choose which sample file you need.
