Summarize FLAC recordings by giving the file to Potok in Telegram, and a short digest of the talk comes back in 1 reply. Send one interview rather than a whole album, since mixed material muddles the summary. Lossless sound will not rescue muffled speech, so read the transcript too before trusting a detail.

How to summarize FLAC recordings
- Start with the bot. Go to @potok_now_bot in Telegram, then send your .flac recording. The limit is 2 GB per file, and the Upload button of the mini app is the way to send a big one.
- Keep the format in mind. The flac command-line tool encodes audio to FLAC streams (flac encoder tool).
- Ask for the digest. Use the summary button under the transcript for a short digest, and read it next to the full text before you share it.
- A useful detail. RFC 9639 allows 1 to 8 channels, bit depths from 4 to 32 and sample rates from 1 to 1048575 Hz.

What to avoid with FLAC
| What goes wrong | Effect | What to do |
|---|---|---|
| Sending a FLAC album instead of one interview | The summary mixes songs and talk into one digest | Send only the FLAC file with the speech |
| Expecting FLAC audio quality to fix muffled speech | Lossless storage keeps the muffled sound exactly as it was | Record closer to the speaker for clearer words |
| Skipping a check of the transcript after the summary | Misheard names stay in the digest | Check names and terms in the transcript |
| Labeling several FLAC files alike and mixing up their summaries | You attach the wrong digest to a recording | Name each file clearly and keep the digest beside it |
