SPX
SPX, often referred to as Speex, is an open-source audio compression format designed for speech. It's known for its efficiency in compressing speech at low bitrates, making it ideal for voice over IP (VoIP) and voice recording applications. Speex supports various encoding modes, including wideband and narrowband, and utilizes techniques like psychoacoustic modeling to achieve good quality while minimizing file size. While not as common for general audio as MP3 or AAC, SPX is a specialized codec for voice.
AU
The AU (or .au) audio file format is a simple, uncompressed audio format originating from Sun Microsystems. It typically stores 8-bit or 16-bit pulse-code modulation (PCM) audio data and is often used in Unix-like systems and for basic audio playback. AU files are characterized by their header, which contains information about the audio encoding, sample rate, and number of channels. While uncompressed, it's a straightforward format for storing raw audio samples.
なぜ変換するのか SPX → AU?
You might need to convert SPX to AU for several reasons. If you have recorded speech using the efficient Speex codec (SPX) and need to use it with software that doesn't natively support SPX, converting to the more universally compatible AU format is essential. This could be for audio editing, archiving older sound clips, or integrating speech recordings into projects that require standard audio formats. Converting ensures broader compatibility and easier playback across different operating systems and applications, making your SPX audio data accessible and usable in a wider range of contexts.
SPX vs AU
SPX (Speex) and AU are distinct audio formats. SPX is a highly compressed, lossy format optimized for speech, offering significant file size reduction, especially at lower bitrates, making it ideal for streaming and storage of voice. AU, on the other hand, is typically an uncompressed or minimally compressed format, often used for raw audio data, offering high fidelity but larger file sizes. Converting SPX to AU means moving from a specialized, compressed speech format to a more general, less compressed audio format. This conversion is useful when compatibility with standard audio tools is prioritized over maximum compression for speech.
