I’m preparing a music-trivia game and need clean, ready-to-play clips pulled from both audio tracks and music videos. For every title I supply, please isolate the chorus or main hook and trim it down to a tight 20–30-second segment. Audio levels should stay consistent across all files, with a quick fade-in and fade-out so the cuts feel intentional rather than abrupt. I’ll deliver a list of songs plus links to the official videos. Return two separate folders—one for audio (MP3) and one for video (MP4 or MOV, whichever keeps the best quality). Each file should be named clearly so I can drop them straight into my quiz software. So i have my own app so simple for cutting songs and video songs, its quick and easy i just lack time to do it.

AUDIOBOOK EQ BALANCING Need pro sound editor to try balancing audiobook recorded in multiple studios. Sample clip attached. If you can get the sample to sound cohesive, you got the job.

I have a 30–60-minute home video that I need moved onto a standard DVD-R. While the picture is fine, the audio track needs serious help: voices are too low, and wind plus other background noises make parts of the dialogue hard to follow.

Here’s how I picture the workflow: • You receive the source file (or tape if you can digitise it). • You perform an advanced audio restoration pass—EQ, noise reduction, compression, whatever tools you consider best (iZotope RX, Audition, etc.). • You author the corrected video to a DVD-R with a simple menu or direct play, then ship or se...

I am building a fully self-hosted, real-time voice assistant on top of LiveKit.
