Include Note Pauses in Lecture Playback Time — Free
Speeding a recording does not speed your note-taking pauses. Estimate the whole study block by applying playback speed only to the recorded portion.
The proof surface
Reading-load planners allocate pages. This separates accelerated media time from real-time pauses, avoiding the common mistake of dividing the entire study block by speed.
Why the flat version breaks
Speeding up the notes on paper
Only the recording changes duration with the playback multiplier.
Using the same pause estimate everywhere
Worked problems and review lectures require different handling.
Confusing exposure with understanding
Finishing the recording does not establish recall.
How to work the playback tachograph
Use the playable duration excluding optional sections you have deliberately skipped. Do not subtract unknown breaks simply to make the schedule fit.
Time one representative lecture with pauses for notes, rewinds and worked examples. Put those extra minutes in the second column, outside the speed calculation.
Choose the rate at which you can follow this subject. Faster playback is not a learning target and may increase the pauses needed to understand difficult material.
A sixty-minute lecture at 1.5× plus twenty pause minutes takes sixty minutes, not about fifty-three. Compare the estimate with a real session and adjust future pause allowances.
What the playback tachograph replaces
| Question | Before | Visible working |
|---|---|---|
| Speeding up the notes on paper | Only the recording changes duration with the playback multiplier. | Estimate pause time separately |
| Using the same pause estimate everywhere | Worked problems and review lectures require different handling. | Use a comprehensible speed |
| Confusing exposure with understanding | Finishing the recording does not establish recall. | Reserve the resulting block |
A local arithmetic aid replaces hand calculation, not expert review. No paid AI service is needed.

FIRST-LOAD
Input is processed locally. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
This estimates time, not learning outcomes or an ideal playback speed. Ask an instructor for help when repeated sections remain unclear.
Data note: Everything runs in this browser tab on the playback tachograph: your lecture | recorded minutes | note-pause minutes stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Go deeper: the companion app files the same reading as a index card with a stamped header
The article demo above runs without limits. The companion app keeps a local history, exports the rows as CSV, prints the playback tachograph reading, and holds your drafts on this device — one free run, then $ 4 one-time for the layer that keeps filing.
The playback tachograph reading is complete for free. The optional $4 layer adds print, row CSV and the last five local reading summaries; it does not add hidden answers. Checkout is not configured yet; the article demo remains unlimited.

What this is built on
- Method: Choose the rate at which you can follow this subject. Faster playback is not a learning target and may increase the pauses needed to understand difficult material.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-27, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Before: Only the recording changes duration with the playback multiplier. After: the playback tachograph shows the working beside each named row so the reader can change the assumption and inspect the consequence.
Optional AI formatting, not calculation
For this playback tachograph, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a playback tachograph. Return plain rows only: lecture | recorded minutes | note-pause minutes. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: lecture | recorded minutes | note-pause minutes. No AI response is executed as code.
