Hi CSAF — thanks again, and I'm the creator.

Both of your notes are fixed in the latest downloadable sample. The voiced-only counter covers the earlier "a"/"I" on an even absolute index case, and the new build also resets that counter at each word boundary (on space), so the first voiced letter of every word blips — including the "a" and "m" in "Got a map".

Please grab the updated zip from the itch page and try it. If any line still feels off after that, tell me which line and I'll tune the default.

Thanks — that is a sharp catch, and you are right about ci % 2.

I have updated the sample so the blip cadence uses a separate voiced counter that only increments when a character is actually voiced. Spaces are always silent; with skip_punctuation on (the new default), punctuation is silent too and does not advance that counter. So a one-letter word like "a" or "I" no longer goes missing just because its absolute index was even.

The settings are now exported on the Main node:

- char_interval (default 0.05)

- blip_every_n_chars (default 2)

- skip_punctuation (default true; set is . , ! ? ; : … ' " -)

- pitch_min / pitch_max (defaults 0.95 / 1.05, applied as pitch_scale = randf_range(...) on each blip)

The downloadable zip on this page is already updated with that build. If you try it and the rhythm still feels off on a specific line, tell me which line and I'll tune the defaults.

— Yuanqian Ye

Thanks, good questions! Right now it skips spaces and plays a blip on every second visible character, so at the default speed (one character per 0.05 s) you get about 10 blips a second instead of 20. Punctuation still blips, and there's no pitch variation yet. Both are hardcoded in `_process()`, not exposed as settings.

If you want both of your suggestions, this replacement for line 19 skips punctuation too and adds a small random pitch shift:

var c := s[ci-1]
if c != " " and not ".,!?;:'\"-".contains(c) and ci % 2 == 1:
    p.pitch_scale = randf_range(0.94, 1.06)
    p.play()

I'll turn the interval, the punctuation skip and the pitch range into exported settings in the next update.

I'm the creator. If you run a haunted house, crypt or asylum session, this is a set of horror ambience built for fading layers up and down. I made it for video games, and I'm sharing it here because the scenes and stems may also suit a GM's soundboard. I haven't playtested it at a table.

What's in it: 57 sounds, every one as WAV + OGG.

• 6 seamless 60-second scenes: Haunted House, Crypt / Catacombs, Foggy Graveyard, Abandoned Asylum Hallway, Cursed Forest, Flooded Basement
• each scene as a full mix plus 4 stems (bed, air, detail, presence) that add up to the mix, so you can start with the bed and add layers as the danger gets closer
• heartbeat and tension loops, 5 jump-scares, 4 reveals, risers, impacts, door creaks and knocks
• no screams and no spoken words, so it will not clash with your own monsters or NPC voices

Hear it first in your browser (free, no download): there is a web demo at the top of the page.

Free version: Haunted Atmosphere FREE Lite has 10 of the 57 sounds. https://yetiancai.itch.io/haunted-atmosphere-free-lite

Good luck making something gloriously bad!

Adding to the good tips above, a few more things that made text blips feel less robotic for me:

- Don't blip on every character. Play a sound every 2nd or 3rd letter, skip spaces and punctuation, and add a short pause at commas and full stops. That alone makes it read like speech rhythm instead of a typewriter.

- Pick from 3 to 5 slightly different pitches per character instead of repeating one tone, and keep each blip short (under about 50 ms) with a few milliseconds of fade-in so it doesn't click.

- Use a softer waveform than a raw square: a sine plus a little of the 3rd and 5th harmonic, or a triangle, then low-pass it.

- Give each speaker a fixed base pitch and timbre, so the voice tells you who is talking.

- For settings: a separate "Dialogue voice" volume slider (or an on/off toggle) next to SFX, so players can keep sound effects but turn the voices down.

I'm the creator. Haunted Atmosphere Free Lite is free for everyone in the GoedWare Halloween jam. It's 10 sounds from my horror ambience pack:

- 2 full scene loops (Haunted House, Foggy Graveyard, 60 s, seamless)

- 2 tension loops (heartbeat 60 bpm, tension pulse 72 bpm)

- a jump-scare, a reveal stinger, a riser, an impact, a door creak and a knock

Every sound comes as WAV + OGG. The loops have their loop points embedded, so they drop straight into Godot, Unity or GameMaker.
