Audio Size Preview:

Our audio size preview feature provides an estimate of the file size after conversion, regardless of the format. This tool helps users gauge whether the new file size meets their needs and storage capabilities, making it easier to decide on the conversion parameters for formats ranging from compressed to uncompressed audio.

Custom Quality:

Our conversion tool offers customizable options for audio bitrate and sample rate, allowing users to fine-tune the quality of their audio files. Whether you're converting to a format for professional use or casual listening, these settings provide the flexibility to optimize audio quality according to your specific requirements.

Fast conversion:

We value your time. Our service efficiently converts your AU files to high-quality WAV format, allowing for quick access to your uncompressed audio files.

Cross-Platform Accessibility: is accessible on any device with an internet connection. Convert AU to WAV effortlessly on your desktop, tablet, or smartphone, anytime and anywhere.

Privacy Protection:

Your privacy is our top concern. We ensure that your files are never stored on our servers, maintaining the security and confidentiality of your data.

Local Conversion:

Enhance your security by converting AU to WAV directly on your device. Our local conversion process prevents your audio files from being uploaded to our servers, protecting the confidentiality of your files, especially important for sensitive or personal data.

Audio parameters

Audio Bitrate:

Audio bitrate is a key determinant of audio quality and file size, measured in kilobits per second (kbps). Common bitrate values range from 128 kbps, suitable for standard quality, to 320 kbps for high-quality audio. In professional settings, bitrates can be even higher. Our tool allows you to choose from a variety of bitrate options, enabling you to strike the perfect balance between sound quality and file size based on your specific needs, whether it's for casual listening or high-fidelity audio playback.

Sample Rate:

The sample rate, measured in hertz (Hz), defines how many times the audio is sampled per second. Standard CD-quality audio uses a sample rate of 44.1 kHz, while professional audio recordings often use 48 kHz or higher, up to 192 kHz for high-resolution audio. Our conversion tool lets you adjust the sample rate to suit your requirements, offering the flexibility to choose between standard quality for everyday use and higher rates for detailed, professional-grade audio production.

Introduction to WAV Format

Definition of WAV

WAV, or Waveform Audio File Format, is a standard audio format for storing an uncompressed audio bitstream on PCs. It's commonly used in professional audio recording and editing due to its uncompressed, high-quality audio capability. WAV is favored in settings where preserving the integrity and fidelity of audio recordings is crucial.

High-Quality, Uncompressed Audio

WAV files offer the highest quality of sound as an uncompressed audio format, making them ideal for professional settings where audio quality is paramount. This high fidelity comes with the trade-off of larger file sizes compared to compressed formats like AU.

Primary Use in Professional Audio

WAV is commonly used in music production, audio engineering, and other fields requiring high-quality audio. It's particularly valued for its audio fidelity in music studios, sound design, and other professional audio applications.

Introduction to AU Format

Definition of AU

AU is a simple audio file format primarily used on Sun Microsystems and UNIX-based computers. Known for its basic audio data structure, AU is often used for straightforward audio data storage and is recognized for its compatibility with various UNIX applications.

Simple and Effective Audio Format

The AU format's simplicity is one of its key advantages. Designed to store sound in a compact yet effective way, it's suitable for applications where complex audio file structures are unnecessary. This simplicity ensures easy handling and playback on UNIX systems.

Compatibility with UNIX Systems

AU is highly compatible with UNIX and UNIX-like operating systems, making it a frequent choice for basic audio storage and playback in these environments.

What Happens When Converting AU to WAV

Conversion to an Uncompressed Audio Format

Converting from AU to WAV involves transforming the compressed AU audio file into the uncompressed, high-quality WAV format. This process typically results in an increase in file size but maintains or enhances the audio quality of the original recording.

Increase in File Size

Due to the uncompressed nature of WAV, converting from AU will lead to a larger file size. This is an important consideration for storage and bandwidth, especially when dealing with large collections of audio files.

Retention of High Audio Quality

The conversion to WAV ensures that the audio quality is preserved or enhanced from the original AU file, making it ideal for scenarios where uncompressed audio is required for editing, processing, or achieving the highest fidelity in playback.

Considerations When Converting AU to WAV

Evaluating the Need for Uncompressed Audio

Before converting to WAV, consider whether the need for uncompressed, high-quality audio justifies the increased file size. WAV is ideal for professional audio settings and high-fidelity work but may be excessive for casual listening or on devices with limited storage capacity.

Understanding Storage Requirements

Be aware that converting from AU to WAV will significantly increase the file size. Ensure that you have adequate storage capacity, especially if converting a large number of files or working with high-resolution audio.

Selecting Appropriate Conversion Software

Choose a conversion tool that can effectively handle the AU to WAV conversion, ensuring the integrity of the audio data is maintained during the process. Software that specializes in high-quality audio conversions is recommended for the best results.

Security in Conversion

For audio files with sensitive content, opt for a service that ensures privacy and security. performs AU to WAV conversions directly on your local device, safeguarding the confidentiality and security of your files. This local conversion method prevents your data from being uploaded to external servers and protects it throughout the conversion process.
