# Multisound

*/Startups/Multisound*

## Startup Overview

Video editors and podcast producers face constant friction when merging multicam shoots lacking jammed timecodes. Manual alignment in a digital audio workstation takes hours, while overlapping dialogue across independent microphones creates unusable audio bleeds. This browser-native engine ingests unlinked raw audio and video feeds to automatically synchronize every track.

The system identifies and corrects audio drift at the frame level without relying on embedded timecodes. Beyond basic alignment, it isolates overlapping speaker stems from mixed feeds, separating cross-talk into clean, individual channels. Editors drag and drop raw files into the web interface and export a perfectly synced, multi-track timeline ready for final mixing.

Traditional sync workflows rely on desktop plugins like Red Giant PluralEyes or tedious manual waveform matching in a DAW. Text-based editors like Descript handle single-mix transcriptions but fail at complex multi-source phasing. By combining timecode-free drift correction and stem isolation natively in the browser, the platform eliminates the pre-edit sync bottleneck entirely.

## Startup Offer

**Proof**:
- Target: Reduce multi-cam podcast sync time from 45 minutes to under 2 minutes.
- Target: Achieve zero-drift alignment on 3+ hour continuous unscripted documentary shoots.
- Target: Enable solo creators to completely isolate and recover overlapping dialogue previously considered unusable.
**Tiers**:
- Name: Solo Editor · Price: ~$15–$25/mo · Inclusions: Up to 15 hours of multi-source audio alignment and basic overlapping stem isolation per month.
- Name: Post-Production Pro · Price: ~$45–$85/mo · Inclusions: Up to 60 hours of processing, continuous drift correction, lossless WAV exports, and XML/AAF timeline handoffs.
- Name: Studio Unlimited · Price: ~$150–$250/mo · Inclusions: Unmetered alignment processing, batch project uploads, and priority compute queuing for feature-length sessions.
**Guarantee**: Frame-accurate synchronization and drift correction on any multi-cam shoot up to 5% drift, or the consumed processing minutes are automatically refunded to your account.
**Business Function**: ProvideService
**Objection Handlers**:
- Objection: Browser-based processing will take way too long to upload. Rebuttal: The app is designed to extract the audio layer locally in your browser, uploading only lightweight audio files instead of gigabytes of video.
- Objection: My camera scratch audio is heavily distorted or practically inaudible. Rebuttal: The engine aligns using phonetic and vocal frequency signatures, not just raw volume peaks, syncing reliably even with degraded scratch tracks.
- Objection: Overlapping speakers will still bleed into each other's tracks. Rebuttal: The AI stem isolation is built to lock onto individual voice signatures, separating simultaneous speech into fully independent, clean tracks.
- Objection: I don't want to lose my original bit depth or sample rate. Rebuttal: The platform is designed to process and export lossless WAVs that strictly inherit your original file specifications.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- Target Pilot 1: A 14-day sprint with a daily video podcast team. Target result: Validate that the local-browser audio extraction prevents massive video file upload bottlenecks, allowing them to sync daily multi-cam episodes in under 2 minutes each.
- Target Pilot 2: A 30-day deployment with a boutique post-production house handling feature-length sessions. Target result: Prove the continuous drift correction maintains absolute frame accuracy over 90+ minute timelines without manual resyncs.
- Target Pilot 3: A test session with a reality TV editing crew dealing with heavy mic bleed. Target result: Demonstrate the overlapping stem isolation successfully separates simultaneous cast arguments into clean, independent tracks.
**Target Metrics**:
- Target: Reduce manual multi-source audio alignment time from 45 minutes to under 2 minutes per session.
- Aim: Achieve zero-frame drift on continuous, unscripted multi-cam shoots up to 3 hours in length with up to 5% natural drift.
- Target: Recover 95% of overlapping dialogue previously classified as unusable by isolating voice signatures into independent tracks.
- Aim: Keep user upload wait times under 60 seconds per hour of video by extracting the audio layer locally in the browser.
**Target Case Studies**:
- Target Case Study: A mid-sized podcast production agency editing 10+ multi-cam shows per week. The transformation replaces manual waveform nudging with automated XML/AAF timeline handoffs, reducing per-episode sync preparation from 45 minutes to under 2 minutes.
- Target Case Study: An independent documentary film crew managing 3-hour unscripted continuous shoots. The transformation uses phonetic frequency signatures to automatically align heavily distorted camera scratch audio and correct multi-camera drift without manual intervention.
- Target Case Study: A solo YouTube creator filming interview content. The transformation salvages previously unusable overlapping dialogue by applying AI stem isolation to separate simultaneous speakers into clean, independent tracks.
**Testimonial Targets**:
- Target Testimonial from a Post-Production Audio Engineer: Expresses relief that the XML timeline handoffs drop perfectly into their DAW with frame-accurate sync, while strictly preserving their original bit depth and lossless WAV sample rates.
- Target Testimonial from a Documentary Video Editor: Shares amazement that the engine aligned their heavily degraded camera scratch audio using phonetic signatures, saving them days of manual clip nudging.
- Target Testimonial from a Podcast Agency Owner: Highlights excitement over how the batch project uploads and priority compute queuing allowed their team to process a massive backlog of multi-cam episodes without workflow bottlenecks.

## Startup Top Risks

**Risks**:
- Severity: existential · Description: Adobe or Blackmagic integrates zero-timecode drift correction directly into Premiere or Resolve, removing the workflow need for a standalone browser tool. · Mitigation Status: unmitigated
- Severity: high · Description: Browser memory limitations cause runtime crashes when processing multi-gigabyte, uncompressed WAV files for feature-length projects. · Mitigation Status: in-progress
- Severity: high · Description: Overlapping speaker isolation introduces digital artifacts that cause the exported audio stems to fail professional broadcast quality standards. · Mitigation Status: in-progress
- Severity: moderate · Description: The drift correction algorithm fails to sync feeds recorded in heavily noisy environments, forcing users to revert to manual DAW alignment. · Mitigation Status: unmitigated
