Clock tick countdown

Six small ticks create a pause before a decision.

Anticipation, quizzes, and short countdowns · 3.5 seconds

1 Hear it

Start with the whole sound. What action does it suggest before you read how it was made?

The first take

Hear the separate layers

A layer, also called a stem, is one ingredient saved on its own. These share a timeline; keep their leading silence when combining them.

2 Make it with your AI

Ask your assistant: “Can you run Python and return WAV files here?” If it can, use the starter prompt below and ask it to return the audio, source and settings. Download the files it makes.

If it only returns text, ask for the complete script and follow the local steps below. A written response is not an audio file.

Make an original clock-like countdown for a podcast quiz.
Create six short, dry ticks with a small alternating tick/tock pitch
difference and a light mechanical click. Keep the perspective close
and the stereo width narrow. Do not add an alarm or a special last note.
Use a 3.5-second file. Start at 0.12 seconds and space the six tick
starts 0.55 seconds apart, leaving silence after the final decay.

Use Python's standard library and original synthesis only. Save separate
layers, a 48 kHz / 24-bit stereo master, a mono fold-down, and a 16-bit
stereo WAV preview. Leave 6 dB of sample-peak headroom. Save the source,
a JSON preset with a fixed seed, a manifest, and SHA-256 checksums.

If you can run the code, render and verify the files. Otherwise return
complete code and local commands, and say what remains unexecuted.
Preserve the first take as v001 so a later experiment cannot overwrite it.

Your assistant may produce a different implementation. Use our kit for the reference sound.

What we actually did

Our local coding assistant wrote and ran Python on a Mac. It used tones and repeatable noise, without an audio-generation service.

Make each tick from a damped tone and noise click.
Alternate the body pitch slightly.
Place six ticks at regular intervals.

Reproduce our sound: files and local steps

A fresh prompt can produce a different implementation. To reproduce these takes, give your assistant the complete kit and ask it to use the supplied generator and presets. If it cannot open ZIP files, extract the kit first and provide its files.

Includes both takes, separate layers, source, settings and verification tools. You do not need access to our repository.

Or run it yourself: extract the ZIP, open Terminal in the folder containing README.txt, effects/, scripts/ and library/. Use Python 3.10 or later. No Python packages or API keys are needed.

python3 effects/009-clock-countdown/src/render.py --preset effects/009-clock-countdown/presets/v001.json --output tmp/009-clock-countdown-v001

python3 effects/009-clock-countdown/src/render.py --preset effects/009-clock-countdown/presets/v002.json --output tmp/009-clock-countdown-v002

Open each new preview.wav in an audio player. Keep a new output directory for every attempt; the generator refuses to overwrite previous takes.

python3 scripts/verify_library.py --reproduce

The verification command checks the retained files and regenerates both takes. Exact reproduction was tested on Python 3.14.3/macOS; another runtime needs its own check.

3 Change one thing

Does faster spacing add useful anticipation, or hurry the listener?

We tested a specific change: faster ticks. The first take stays available so you can compare.

What changed in the files

Six ticks remain; their spacing changes from 0.55 to 0.38 seconds. Individual tick shapes and final mix gain stay the same.

This is a measured result. No listening preference has been recorded for these takes. Equal peak levels do not guarantee equal perceived loudness.

Read or copy the revision prompt

Prompt text — select and copy, or use the buttons below

Keep v001 unchanged. Copy its preset to v002 and change only
tick_spacing_seconds from 0.55 to 0.38, plus the take label. Keep all
six ticks, their body and click settings, individual noise seeds,
pan, file duration, and -6 dBFS peak target. Do not add a final alarm.
Render both takes and report event timing and level changes. Leave
the choice open until both have been tried against the quiz narration.

Your assistant may produce a different implementation. Use our kit for the reference sound.

This prompt names controls in our supplied source. If your assistant wrote a different generator, ask it to identify the matching control first.

Inspect settings, masters and provenance

tick_spacing_seconds: 0.55 → 0.38. The take label also changes; all other sound settings remain fixed.

4 Decide what works

Try the ticks beneath a quiz pause. Give the listener time to think.

Compare both takes at comfortable playback levels, first alone and then beside narration.
Try the passage without the effect. Keep the version that serves the moment; “neither” is a useful answer.
Describe what you heard before asking for one next change. Preserve your earlier takes.

Keep listening notes
