What is a WAV file?
The Waveform Audio File Format (WAV) is a raw audio bitstream standard developed by Microsoft and IBM, serving as a subset of the Resource Interchange File Format (RIFF) specification. It primarily stores uncompressed Linear Pulse Code Modulation (LPCM) audio data, making it the industry standard for archival and high-fidelity mastering on Windows systems. The format supports varying bit depths and sample rates, with the Red Book standard (44.1 kHz, 16-bit stereo) being the most prevalent implementation.
How to open a WAV file
WAV files enjoy near-universal native support across all major operating systems due to their status as a foundational audio standard. Windows Media Player, Apple QuickTime, and Linux-based media players (via ALSA/PulseAudio) open WAV files by default without requiring external codec packs or third-party software.

What is an AAC file?
Advanced Audio Coding (AAC) is a lossy digital audio compression standard defined by ISO/IEC 13818-7 (MPEG-2) and ISO/IEC 14496-3 (MPEG-4). Developed by a consortium including Bell Labs, Fraunhofer IIS, and Dolby Laboratories as the successor to MP3, AAC utilizes the Modified Discrete Cosine Transform (MDCT) algorithm and perceptual noise shaping to discard imperceptible signal components. It supports up to 48 audio channels, arbitrary sample rates, and utilizes extensions such as Spectral Band Replication (SBR) to achieve higher fidelity at lower bitrates than predecessor formats.
How to open an AAC file
AAC serves as the default audio container for Apple's iTunes and iOS devices, ensuring native support within the macOS Core Audio framework and Apple Music. Windows 10 and 11 provide native decoding support via the Groove Music and Windows Media Player applications. For cross-platform playback or advanced stream analysis, users should utilize VLC Media Player or FFmpeg, which contain the necessary libavcodec libraries to decode AAC streams without external codec packs.
