Audio files in Windows Movie Maker can be imported in which of the following formats?WMAMP4WAVMP3MP2

Windows Movie Maker supports the import of audio files in the following formats:

1. WMA: Windows Media Audio is a series of audio codecs and their corresponding audio coding formats developed by Microsoft. It is a proprietary technology that forms part of the Windows Media framework.

2. WAV: Waveform Audio File Format is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs. It is an application of the Resource Interchange File Format (RIFF) bitstream format method for storing data in "chunks", and thus is also close to the 8SVX and the AIFF format used on Amiga and Macintosh computers, respectively.

3. MP3: MPEG Audio Layer III or MP3 is a coding format for digital audio. Originally defined as the third audio format of the MPEG-1 standard, it was retained and further extended—defining additional bit-rates and support for more audio channels—as the third audio format of the subsequent MPEG-2 standard.

4. MP2: MPEG-1 Audio Layer II or MP2 is a lossy audio compression format defined by ISO/IEC 11172-3 alongside MPEG-1 Audio Layer I and MPEG-1 Audio Layer III (MP3). While MP3 is much more popular for PC and internet applications, MP2 remains a dominant standard for audio broadcasting.

However, MP4 is not supported as an audio file in Windows Movie Maker. MP4 is a digital multimedia container format most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images.
