The MOV file format supports audio, video, text, images, and sprites. WAV is a digital audio file format used in Windows. QuickTime can convert MOV to WAV, but other software can also be used. The conversion process involves choosing options for sample size, channels, frequency, and rendering quality. Many converters are available online, but they may be OS and version specific.
MOV (.mov) is a digital file format developed by Apple and is used in the QuickTime® software application, as well as by many digital cameras. The container-like structure of MOV differentiates it from other media formats and makes it capable of supporting streaming video over the Internet and containing a collection of disparate content on distinct tracks. The contents that MOV can contain include audio and video, but also text, images and sprites — independent graphic objects. WAV (.wav) is the Microsoft® Windows® waveform audio file format and is used for digital audio. Therefore, when converting from MOV to WAV, data that is not audio may be lost, but this type of conversion can be useful for adapting audio to particular playback devices, such as Windows® system sounds.
One way to convert MOV to WAV is within QuickTime®. This may require QuickTime® 7 and the Pro version. With a file open, using File > Export, you can then choose “On Air” for export. You can click “Save” or explore other options.
More detailed options become visible by clicking the “Options” button or using the “Default Settings” drop-down menu. The “Options” button tells you that the format of the audio will be switched to Linear PCM – there’s no choice about that – but you can control the sample size and choose between Little Endian, Floating Point and Unsigned. You can also choose stereo or mono channels, kHz frequency and rendering quality.
You can also play a preview to see the impact of your setting choices and play the source file so you can compare. This is especially important because within a MOV file, sound can be in a variety of formats. These include AAC (Advanced Audio Coding), MPEG 4 (Moving Pictures Experts Group) — High Efficiency AAC or Low Delay AAC, Apple Lossless, AMR NB (Adaptive Multi-Rate Narrowband), IMA (also known as IMA4 and IMA-ADPCM — Interactive Multimedia Association; Adaptive Differential Pulse Code Modulation), Linear PCM (Pulse Code Modulation), Qualcomm® PureVoice® and iLBC (Internet Low Bit Rate Codec).
If you don’t have access to QuickTime®, you can find freeware and paid software to easily convert MOV to WAV by searching the Internet. Most converters are OS and version specific; that is, they will work on Mac® computers or Windows® computers, not both, and with some particular versions of the software, but not others. Many programs that convert MOV to WAV also convert other formats, so if you already have any type of converter, check if it will handle these file formats. The steps will be similar to those described for QuickTime®, except that it usually begins by finding a file in a browser or dragging and dropping it onto the interface, rather than opening it.
