Input Format
What is WAV?
WAV (Waveform Audio File Format) is an uncompressed audio format that stores high-quality sound, often in PCM form. The .wav extension is common in recording, editing, and professional workflows.
History
WAV was introduced by Microsoft and IBM in 1991 as a standard container for raw audio data on Windows systems.
How it works
WAV is based on the RIFF container and typically stores audio as uncompressed PCM samples. This keeps quality high but results in larger file sizes.
How to open WAV files
WAV files can be opened in most media players and audio tools:
- VLC Media Player
- Windows Media Player
- Apple Music or iTunes
- Audacity
- Adobe Audition
- Logic Pro
- Most smartphones and tablets
Tips for working with WAV files
WAV is ideal for editing and archiving, but keep file size in mind:
- Use WAV for recording and mastering before compression
- Choose 44.1 kHz or 48 kHz for standard projects
- Convert to FLAC for lossless compression
- Trim silence to reduce file size
- Export to MP3 or AAC for sharing

Output Format
What is AAC?
AAC (Advanced Audio Coding) is a modern lossy audio codec that delivers better quality than MP3 at the same bitrate. The .aac extension is common in streaming, mobile devices, and video containers.
History
AAC was standardized by the MPEG group in the late 1990s as the successor to MP3 and became the default codec for many platforms.
How it works
AAC uses advanced psychoacoustic models and flexible block sizes to compress audio efficiently while preserving clarity at lower bitrates.
How to open AAC files
AAC plays on most modern devices and media players:
- Apple Music or iTunes
- VLC Media Player
- Windows Media Player
- Android music players
- Foobar2000
- Audacity
- Most smartphones and tablets
Tips for working with AAC files
AAC is a strong choice for streaming and portable audio:
- Use AAC for better quality at low bitrates
- Store AAC in M4A for metadata support
- Avoid re-encoding from AAC to AAC
- Convert to MP3 for older devices
- Keep a lossless master for archiving
