RA
RealAudio (.ra) is an early proprietary audio format developed by RealNetworks, primarily designed for streaming audio over the internet. It uses various compression techniques to reduce file size, allowing for efficient delivery over limited bandwidth connections. While effective for its intended purpose, RA files often require specific players or software for playback and editing, making them less universally compatible than other audio formats. Its adaptive streaming technology was revolutionary for its time.
AU
Audio File Format (.au) is a simple audio file format developed by Sun Microsystems, commonly used on Unix systems. It is known for its simplicity and is often uncompressed, meaning it stores raw audio data without significant loss of quality. AU files can contain various types of audio data, including 8-bit µ-law encoded audio, which is common in voice recordings. Its straightforward structure makes it easy to parse and work with in many audio processing applications.
なぜ変換するのか RA → AU?
You might need to convert RA to AU for several reasons. Compatibility is a major factor; AU format is more widely supported by various audio editors, media players, and operating systems than the proprietary RealAudio format. If you have archival RA audio files or need to integrate them into a project that doesn't support RA, converting to AU ensures broader accessibility and usability. Additionally, for applications requiring uncompressed or minimally processed audio, AU offers a cleaner alternative to the compressed RA stream, preserving more of the original sound detail.
RA vs AU
The primary difference between RA and AU lies in their design and compression. RealAudio (.ra) is a proprietary, compressed format optimized for internet streaming, often involving variable bitrates and specific codecs. This can lead to potential quality loss and limited compatibility. In contrast, the AU format is a simpler, often uncompressed, format common in Unix environments, prioritizing raw audio data and wide compatibility. While RA excels at efficient streaming, AU provides a more direct and universally accessible audio representation, making it ideal for editing and archiving where maintaining the purest audio signal is paramount.
