Finally AudioCoder is getting updated after a whole year time. AudioCoder is a audio transcoder software based on MediaCoder, with a simplified user interface and optimized setup for audio only transcoding. During the year, MediaCoder has been improved consistently. All the improvements related with audio transcoding have been built into the latest AudioCoder release. By supporting up to 8 parallel tasks, AudioCoder is able to fully utilize the 8 or 16 cores of your cutting edge processor to convert a bunch of music files in a flash. The new version has also added support for Opus audio encoding.
AudioCoder is totally free and there is no limit on batch tasks. So just get it and experience it.
