Convert your AAC audio files to WAV format using our free online tool. While AAC offers good compressed audio quality, WAV provides uncompressed, lossless audio, making it ideal for professional audio editing, archiving, and high-quality applications. No Signup Required.
AAC (Advanced Audio Coding) was designed as the successor to MP3 and generally achieves better sound quality at similar bit rates. It was developed by a group including Fraunhofer, Nokia, and Dolby.
AAC is the default format for Apple devices (iTunes, iPhone, iPad) and is used by services like YouTube, while WAV remains the industry standard for uncompressed audio.
AAC uses "perceptual coding" - removing sound elements that the human ear typically can't perceive, while WAV stores the complete waveform data without compression.
Despite AAC's efficiency, WAV is preferred in professional audio editing and production environments where audio quality is paramount.
Converting AAC to WAV involves a process called "decoding" - where the compressed AAC format is decoded back to uncompressed PCM audio data.
During this process, the decoder reconstructs the audio waveform based on the information stored in the AAC file.
WAV files typically use PCM (Pulse-Code Modulation) encoding at 16-bit or 24-bit depths with common sample rates of 44.1kHz or 48kHz. This results in much larger file sizes compared to AAC.
While audiophiles prefer uncompressed formats like WAV, the differences between high-quality AAC and WAV may not be noticeable to casual listeners.
WAV files are typically 10-15 times larger than their AAC counterparts, making them less suitable for portable devices with limited storage.
Pro Tip: Converting from AAC to WAV is ideal when you need to edit audio professionally or archive at the highest possible quality. While WAV files are much larger, they provide uncompressed audio that's perfect for post-processing.
WAV is an uncompressed audio format that provides lossless audio quality. Converting from AAC to WAV is useful for editing purposes, archiving high-quality audio, or when you need the raw audio data for professional applications.
Converting from AAC (which is a lossy format) to WAV won't improve the original quality, but will preserve all the information from the AAC file without further loss. The WAV file will be larger but won't introduce additional compression artifacts.
Conversion time depends on the original file size. Most conversions complete within a few minutes or less.
