What is a VOC file?
The Creative Voice (VOC) file format is a legacy audio standard developed by Creative Technology specifically for the Sound Blaster series of hardware sound cards in the 1990s. The file structure comprises a 26-byte header followed by a sequence of data blocks containing audio information, typically encoded in 8-bit Pulse Code Modulation (PCM) or varying forms of ADPCM (Adaptive Differential Pulse Code Modulation). It was historically used to store digitized voice data and sound effects in MS-DOS environments.
How to open a VOC file
Modern operating systems do not natively support the proprietary VOC format. Playback and conversion require specialized audio editing software or robust media players. Audacity (using the FFmpeg library) allows for importing and converting VOC data to modern standards, while VLC Media Player and Nullsoft Winamp offer playback capabilities.

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.
