What Is Audio Extraction
Audio extraction in 12scribe lets you take any marker and save its audio segment as a separate file. Every marker has a start time and an end time that define a window within the full recording. When you extract audio, 12scribe cuts that exact segment out and creates a standalone audio file you can share, export, or use independently.
Think of it like highlighting a sentence in a book and then photocopying just that highlight. The original recording stays untouched — extraction is non-destructive. You get a clean copy of the specific moment you care about, without the surrounding audio. This is useful in many workflows: pulling a key quote from an interview, isolating a professor's definition of a term, saving a decision from a meeting, or creating a highlight reel from a podcast recording session.
The quality of the extracted clip matches the original recording exactly. There is no re-encoding or compression — 12scribe copies the audio data directly from the source file, preserving full fidelity.
How to Extract
Extracting an audio clip takes just a few taps:
- Open the recording that contains the marker you want to extract.
- Find the marker in the marker list. You can scroll through the list or use the filter to narrow it down by marker type.
- Tap on the marker to select it, then tap the Extract Audio option.
- 12scribe processes the extraction and creates a new audio file covering the marker's start-to-end time range.
- Once complete, you can play the extracted clip, share it via the iOS share sheet, or save it to Files.
The extraction process is fast — even a five-minute segment from a two-hour recording takes only a few seconds to create. You can extract multiple markers from the same recording, and each one becomes its own independent file.
For best results, make sure your marker boundaries are set accurately before extracting. If the start or end time is slightly off, the extracted clip will include extra audio or cut off too early. Use the boundary adjustment tools to fine-tune the marker's start and end times before running the extraction.
Use Cases
Audio extraction fits naturally into several common workflows:
- Sharing a key quote — Pull a 30-second clip of a professor's thesis statement or a speaker's main argument. Share it with classmates or colleagues via Messages, email, or AirDrop without sending the entire recording.
- Podcast highlights — If you use 12scribe to record podcast sessions, extract the best moments as standalone clips. These are ready to post on social media or use as teasers for upcoming episodes.
- Study flashcards — Extract short audio segments of definitions, formulas, or foreign language phrases. Pair them with flashcard apps that support audio attachments for an effective review workflow.
- Meeting decisions — After a meeting, extract the markers where decisions were made or action items were assigned. Share those clips with team members who missed the meeting — far more efficient than forwarding a two-hour recording.
- Evidence and documentation — Researchers and journalists can extract specific interview segments as citable audio evidence, keeping the clips organized separately from full-length source recordings.
You can also use extraction alongside 12scribe's sharing feature to send individual clips to people who do not have the app. The recipient gets a clean audio file they can play in any standard media player.
File Format and Storage
Extracted audio clips are saved in M4A format (AAC encoding), which provides excellent audio quality at a compact file size. M4A is widely supported across iOS, macOS, Windows, and Android — recipients can play the file without installing any special software.
Each extracted clip is stored within the app and can be accessed from the marker's detail view. You can also export clips to the iOS Files app, iCloud Drive, or any third-party cloud storage through the standard share sheet. The file name includes the marker title and timestamp for easy identification.
Storage-wise, extracted clips are lightweight. A one-minute clip typically occupies 500 KB to 1 MB depending on audio complexity. Even if you extract dozens of clips from a long recording, the total storage impact is minimal compared to the original full-length audio file.
If you edit a marker's boundaries after extraction, the previously extracted file remains unchanged. You would need to extract again to get an updated clip with the new boundaries. This is by design — extracted files are snapshots, not live references to the original recording.
