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 swiftly converts your MOV files to high-quality AU format, ensuring quick access to your audio files.

Cross-Platform Accessibility: is accessible on any device with an internet connection. Convert MOV to AU easily on desktops, tablets, or smartphones, anytime and anywhere.

Privacy Protection:

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

Local Conversion:

Convert MOV to AU directly on your device for enhanced security. Our local conversion process prevents your videos 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 AU Format

Definition of AU

AU is a simple audio file format commonly used on Unix-based systems. It is known for its straightforward design and is used for efficiently handling a variety of basic audio recordings and sounds.

Basic and Efficient

Despite its simplicity, the AU format is effective for basic audio tasks, offering decent sound quality and efficient data handling for various applications.

Compatibility with Unix Systems

Primarily used in Unix environments, the AU format is compatible with various Unix applications, making it a practical choice for users in these systems.

Introduction to MOV Format

Definition of MOV

MOV, developed by Apple, is a multimedia container format widely used in QuickTime for storing digital media. It handles various types of digital media, including video, audio, and text, and is known for its high-quality output in multimedia applications.

High-Quality and Versatility

MOV files are preferred for their superior quality in video and audio, supporting various codecs. They are especially suitable for professional video editing and multimedia applications.

Broad Device Compatibility

Though often associated with Apple devices, MOV files are also compatible with a wide range of other platforms, enhancing their utility in diverse multimedia applications.

What Happens When Converting MOV to AU

Audio Extraction

The conversion process involves extracting the audio component from the MOV file. This isolates the audio data, making it ready for conversion to the AU format.

Format Conversion

After extraction, the audio is converted into AU format. This process involves encoding the audio data into AU's simple yet efficient audio format, suitable for basic playback and use in Unix-based systems.

Quality and Efficiency

The focus during conversion to AU is on preserving the original audio quality from the MOV file while ensuring the audio is compatible with AU's format specifications and system requirements.

Considerations When Converting MOV to AU

File Size and Quality

AU files, while simple, can vary in size and quality based on the settings chosen. It's important to select the right balance to meet your specific audio needs.

System Compatibility

Ensure that your target system or software supports the AU format, particularly if you're using non-Unix platforms or devices.

Privacy and Security

For MOV files with sensitive content, choose a conversion service like that ensures your privacy. Our process ensures that conversions are performed locally on your device, keeping your data confidential.
