Parse an Ableton ASD clip file and its warp markers in Python. This module has been tested with.asd files saved with Ableton 9 and Ableton 10.

pip install abletonparsing

Clip class:

• .loop_on - ( bool , READ/WRITE ) - Loop toggle is on
• .start_marker - ( float , READ/WRITE ) - Start marker in beats relative to 1.1.1
• .end_marker - ( float , READ/WRITE ) - End marker in beats relative to 1.1.1
• .loop_start - ( float , READ/WRITE ) - Loop start in beats relative to 1.1.1
• .loop_end - ( float , READ/WRITE ) - Loop end in beats relative to 1.1.1
• .hidden_loop_start - ( float , READ/WRITE ) - Hidden loop start in beats relative to 1.1.1
• .hidden_loop_end - ( float , READ/WRITE ) - Hidden loop end in beats relative to 1.1.1
• .warp_markers - ( list[WarpMarker] , READ/WRITE ) - List of warp markers
• .warp_on - ( bool , READ/WRITE ) - Warping is on
• .sr - ( float , READ/WRITE ) - Sample rate of audio data

WarpMarker class:

• .seconds - ( float , READ/WRITE ) - Position in seconds in the audio data.
• .beats - ( float , READ/WRITE ) - Position in "beats" (typically quarter note) relative to 1.1.1

Ifloop_on is false, thenloop_start will equal thestart_marker, andloop_end will equal theend_marker.
