Fizzy Drink
Fizzy Drink is almost all treble: the 8 to 16 kHz band forms the loudest part of the file, and nothing at all sits below 80 Hz. It is a continuous fine carbonation hiss rather than a series of events, close-miked and very nearly mono. Suits listeners who like bright, dry ASMR texture.

What the recording actually contains
The energy climbs steadily with frequency and peaks in the top octave, which is unusual: almost everything else on this site is loudest somewhere in the low or middle range. Below 250 Hz there is effectively nothing. The bubbles arrive fast enough to merge into a continuous wash rather than resolving into separate pops, so the file barely changes in level across its 32 seconds. Both channels carry nearly the same signal, which keeps the sound tight and close rather than spread out.
How it compares and what to pair it with
Among the drink recordings, Pouring Drink is one large event rather than a texture and Ice Cubes is a handful of sparse clinks. This is the only one of the three that behaves like a continuous bed. Its nearest relative on the site by spectrum is generated blue noise, which also leans to the top of the range. See the sound library index for the rest.
A file this bright is easy to push too far. Start well below where you think you want it, and if it feels sharp, give it a foundation with the Fizzy Drink and brown noise blend in the free sound mixer.
Frequently asked questions
Why does Fizzy Drink sound so bright?
Because its loudest measured band is 8 to 16 kHz, the top octave of hearing, and it carries no energy at all below 80 Hz.
Are there separate bubble pops?
Not distinctly. They arrive fast enough to merge into a continuous hiss across the whole loop.
Will it sound the same on every device?
No. Its content sits where speaker response and personal hearing vary most, so small speakers and older ears will hear noticeably less of it.
What volume should I use?
Start low. Bright, dense high-frequency sound can feel light while still becoming tiring, especially on headphones.
