About AAC

AAC (Advanced Audio Coding) was developed in 1997 as part of the MPEG-2 standard (ISO 13818-7) and updated in the MPEG-4 standard in 1999. AAC is the direct successor to MP3 and achieves significantly better audio quality at the same bitrate, using finer psychoacoustic models and MDCT windows with adaptive length. AAC supports sample rates up to 96 kHz, up to 48 channels, and HE-AAC (High Efficiency) for bitrates starting at 24 kbps, making it the standard for streaming services like YouTube, Netflix, and Apple Music. Apple introduced AAC as the standard format in the iTunes Store in 2003, establishing it in the mass market. The format is part of MP4 containers and is supported by virtually all modern playback devices and browsers. AAC is the better choice over MP3 at equivalent bitrates and should be preferred for new audio projects.

About WAV

WAV (Waveform Audio File Format) was introduced in 1991 by Microsoft and IBM as part of the RIFF container format for Windows 3.1 and is the standard format for uncompressed audio on Windows systems. WAV stores audio data as raw PCM samples and supports sample rates up to 384 kHz, bit depths from 8 to 32 bits, and up to 6 channels for multichannel audio. The lack of compression results in large file sizes - one minute of stereo CD quality takes up approximately 10 MB. WAV is the reference format in professional audio production, studio recording, and audio forensics, where any form of compression is undesirable. The format also supports compressed codecs like ADPCM, though these variants are less common. On macOS, AIFF serves as the equivalent to WAV, both delivering identical PCM quality. For everyday use, converting to FLAC for lossless archiving or to MP3/AAC for space-saving playback is recommended.

Why convert WAV → AAC?

WAV (Waveform Audio File Format) is an uncompressed audio format with studio quality that stores audio data without any compression. A 3-minute stereo track as WAV is typically 30 MB — completely impractical for mobile use, streaming, or email delivery. Converting to AAC drastically reduces file size (MP3: 90% smaller, FLAC: 50% smaller) and creates a format optimized for mobile players, streaming services, and sharing. AAC makes WAV files practically usable. AAC is the successor to MP3 with better compression, used in M4A containers and MP4 videos.
