ReClock's original purpose is adjust audio clock and media playback rate to video clock so that media plays back without dropped frame and audio in sync with video. ReClock is also often used to "bitstream" PCM audio via WASAPI exclusive mode (that function was added later by James at Slysoft). Configuration is a little bit complicated because we disable the original purpose of ReClock completely. I wish there is a simple audio renderer that supports switching between WASAPI exclusive and shared modes (like JRiver MC's). Initial configuration:+ Audio Interfaces to use for
- PCM: WASAPI Exclusive. This is to avoid resampling PCM by Windows Audio Engine.+ PCM Output
- Sampling rate: Same as input. Don't let ReClock resample the incoming audio.
- Format: 24 bit int padded to 32 (usually 24 bit is not supported by any of AMD, NVIDIA, Intel HDMI audio drivers).
- 16 bit integer for 16 bit sources: checked. This is not important, but...+ Bitstream
- Accept bitstream formats: checked. Otherwise Reclock won't pass compressed audio bitstreams.
- Disable media speed correction with bitstream audio: checked. Avoid frame drops in bitstream audio. (As media adaptation is disabled in the next step, this is redundant.)
Now play a movie with LPCM audio track and click the ReClock icon in the task tray.+ Clock correction
- Slave reference clock to audio: checked. Then "Audio correction" and "System clock correction" will be +0 Hz.+ Media adaptation
- Speed: Original speed
- Locked: checked
So media will be played back at the original speed. Note in "Renderer infos",
- WASAPI excl.
: means that Windows Audio Engine is bypassed.
- bit exact
: means that ReClock does not resample audio.
When you play a movie with compressed audio track,
where you don't have to do anything.Edited by renethx - 3/25/13 at 9:00pm
