Final answer:
Correct option are b and d .The correct audio file compression formats among the options are WAV and MP4. WAV files are uncompressed with high quality, while MP4 is a multimedia container format, also used for compressed audio files.
Step-by-step explanation:
Among the options provided, the audio file compression formats are WAV and MP4. The WAV (Waveform Audio File Format) is a raw audio format that provides high-quality, uncompressed audio but results in larger file sizes. On the other hand, MP4 (MPEG-4 Part 14) is a digital multimedia container format that can store video, audio, subtitles, and images; when referring to audio-only files in MP4 format, it is often termed M4A, which is a subset of MP4 designed for audio. The MP4 format allows for advanced audio coding, enabling compression of audio files with negligible loss of quality. The formats JPEG and STP are not audio compression formats; JPEG is used for image compression, and STP (Standard for the Exchange of Product model data) is related to 3D data exchange.
