मुफ्त ऑनलाइन WVE से OPUS कन्वर्टर

Psion 8-bit A-law. Used on Psion SIBO PDAs (Series 3 and similar). This format is deprecated in SoX, but will continue to be used in libsndfile.

Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end ARM3 processors. Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC, and HE-AAC.
