Budget Uncompressed PCM Audio Storage
Uncompressed audio grows with channel count as well as duration. Estimate the PCM payload at an explicit 24-bit depth before reserving disk space for original recordings.
1 · recording | duration minutes | channel count
FIRST-LOAD
Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. 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.
Data note: Everything runs in this browser tab on the sample spool: your recording | duration minutes | channel count stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: This output uses decimal megabytes, not binary mebibytes. After: the sample spool shows the working beside each named row so the reader can change the assumption and inspect the consequence.

PCM payload estimate at 24-bit depth only. It excludes headers, compression, backups and project-cache overhead.
Paid layer: sample spool print and history
one-time step · the free reading above stays complete
Free tier
- one complete sample spool run in the app
- three samples plus unlimited article-demo runs
- unwatermarked result text and an explicit, user-triggered state link
What $4 one-time adds
- print the sample spool with its row workings
- CSV of decimal megabytes and row explanations
- last five reading summaries saved in this browser profile
$4 once for repeated filing of the sample spool, not for a better answer. Illustrative time basis: avoiding one five-minute manual reformat per saved reading; no market-price or guaranteed-savings claim.
Local history (this device)

Checkout is unavailable until a payment link is configured. The optional unlock is browser-local, profile-scoped and best-effort, not server-verified access. Clearing browser data can remove it; there is no account or cross-device recovery.
Boundary and sources
PCM payload estimate at 24-bit depth only. It excludes headers, compression, backups and project-cache overhead.
- Method: Minutes times sixty times channels times sample rate times three gives payload bytes. Divide by one million for decimal MB; the interview master alone is 777.6 MB.
- 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.
Mechanism: competence-autonomy-loop
Optional AI formatting, not calculation
For this sample spool, 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 sample spool. Return plain rows only: recording | duration minutes | channel count. 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: recording | duration minutes | channel count. No AI response is executed as code.
