Audio Window

Audio Window represents an audio waveform (Wave, MP3, Audio CD,...). Audio Window opens when you load a sound record from disk or when you record something with Wave Recorder. Use mouse or spin edits to select part or the wave for recognition or playback; by default the entire composition is selected.

Only one Audio Window may be opened at a time.

Pause button pauses the playback.

Stop button stops the playback

Transcribe button starts recognition of the selected fragment.

Select from Start button places the selection start at the beginning of the piece.

Select up to End button places the selection end at the end of the piece.

Left channel button selects the left stereo-recording channel for recognition.

Right channel button selects the right stereo-recording channel for recognition.

Combined channels button selects mix of left and right channels for recognition.

Channel difference button selects the difference between left and right channels for recognition; Many recordings has main voice placed at center and arrangements shifted to the right or left channel. By calculating channel difference it is possible to remove primary voice (usually vocal) and leave instruments only. Some karaoke recordings use this method.

Length control also acts as a "Select All" tool.

 

Selecting part of the wave - press primary mouse button down above the Wave pane and move the mouse, then release the button.
