The drivers primarily works on the "Zilog Z80" CPU and is intended to be used in conjunction the game's own "main" sound driver, which is expected to run on the Motorola 68000C (M68K) CPU and send commands to the Mega PCM in order for it to operate. dts file and file Dolby Digital it made me a. Perhaps this is because they don’t require the ad- ditional step of being unzipped and restored to their original PCM data package during real-time during playback. pcm file, for DTS-HD Master Audio it made me a. Interestingly, uncompressed music files such as WAV or AIFF can sound better than lossless compression formats like Apple Lossless or FLAC. So, instead of converting it to wav I chose the option 'Direct Stream Demux'.
Mega PCM is a sound driver for the Sega Mega-Drive / Genesis console that exclusively plays digitized audio samples through an YM2612 sound chip's DAC channel. DVD Audio Extractor can output wav but sometimes it's not acurate.
