18 Month Biannual Technical Meeting Workpackage 5 - Tasks WP5 PartnerRole DIT (Lead)- Pitch / timescale modification, - Source Separation**, - EQ, - Noise Reduction. QMUL- Looping and marking, - Video TSM, NICE- Speech enhancement tools, - subjective quality tools Total 80 PM** developed in WP4 but ultimately an access tool also.

18 Month Biannual Technical Meeting Further Modification Link option for time and pitch scaling Pitch change via transposition (requires Key sig estimate) Time change via tempo change (requires tempo estimate)
7
18 Month Biannual Technical Meeting Workpackage Progress Sound Source Separation Source separation tool is fully developed and ready for integration Problem: DIT IP regulations will not allow code to be open source Solution: DLL for windows release and shared library for Linux release
8
18 Month Biannual Technical Meeting Workpackage Progress Equalisation / Enhancement Equalisation tool is fully developed and ready for integration The equalisation tool can be used to filter out tones and hums which are often present in archival formats such as magnetic tape. Alternately, the tool can be simply used to tailor the sound to a listeners taste and playback system
