It represents the artistic constraint of Daisuke "Pixel" Amaya, who built a system with only 256 bytes of wave data and a 22kHz ceiling yet produced one of the most beloved soundtracks in gaming history. It is a love letter to 8-bit quantization and the warm, nostalgic "fuzz" of lo-fi audio. And it is a rallying cry for the modding community that refuses to let the .org file format fade away, building Rust-based converters and modern C# players just to keep the music playing.

Unlike standard MIDI or modern VSTs, the Organya sound is defined by:

Because Cave Story was so successful, many amateur game developers and musicians aimed to replicate its sound aesthetic. organya22khz8bit

: As the name implies, these are 8-bit samples with a 22kHz sample rate, giving them a distinct, "crunchy" lo-fi retro aesthetic.

Based on your query , you are likely referring to the Organya music format from the indie game Cave Story (Doukutsu Monogatari), specifically requesting a technical specification or feature set for a variant that is 22kHz sample rate with 8-bit depth .

Drum sounds are selected from a set of 42 pre-defined 8-bit samples. Unlike standard MIDI or modern VSTs, the Organya

The "22kHz" refers to a sampling rate of 22,050 Hz. For context, modern CD quality audio is 44.1 kHz, and high-definition music often reaches 96 kHz or higher. Pixel deliberately set his engine to half the standard CD rate. Why?

When you export your final track, set the sample rate to and the bit depth to 8-bit (or use a dithering plugin like Redopter or 8-Bit Shaper ).

To the uninitiated, it is a Da Vinci Code-style riddle. To the faithful, it is the technical heartbeat of an underdog engine that powered one of the most iconic indie games of the millennium: Cave Story (Doukutsu Monogatari).

Because the source files (the WAVs in the Organya22KHz8bit folder) were distributed with PxTone, the sound of Cave Story became a genre. It appears in YouTube remixes, indie game jams, and even soundfonts used by modern producers. The legal status of the samples is a gray area, but because Pixel distributes them for free with his tools, the community generally treats them as "free to use" for non-commercial projects, provided credit is given.

Modern musicians in the chiptune and synthwave scenes are deliberately degrading their audio. VST plugins like Chipsounds and Magical 8bit Plug have presets specifically labeled "22kHz/8bit." Artists are rediscovering that this specific setting is the sweet spot for nostalgia: lower than CD quality, but higher than a telephone (8kHz). It is the "Goldilocks zone" of lo-fi.


Get Your SDR USB Dongle "Frequency Correction (ppm)" (2 Methods)


(Every SDR USB Dongle Has It's Own "Frequency Correction (ppm)" Value)

  1. Follow A "Quick Start Guide" To Setup Your Dongle/Software... (Depends Of Your OS, See Before)
    [And (If Unplugged) Plug Your SDR USB Dongle]

  2. Method 1: With "rtl-sdr":
    - If You Are On Windows, You Can Download From This Link (Download The Latest Version 32 Or 64 Bits):
    https://downloads.osmocom.org/binaries/windows/rtl-sdr/
    (And Unzip Anywhere)

    - If You Are On Linux (Debian/Ubuntu), Just Install Package With Shell Command :
    #> apt-get install rtl-sdr

    - Now Open A Shell (Or "cmd.exe" For Windows, And Go To Unzipped Binaries Folder) And Enter This Command :
    #> rtl_test -p

    - Wait Some Minutes (At Least 5 Or 10 Minutes) And Watch Results (You Can Stop With "CTRL+C") :
    On Results You Have Some "cumulative PPM: XX" Values (XX Is A Number, And Can Be A Negative Number)
    To Find Your SDR USB Dongle "Frequency Correction (ppm)":
    Keep Most Frequently "cumulative PPM: XX" Value (Or Make An Average Of Last "cumulative PPM: XX" Values)

    - In The Example Below, After A Few Minutes, I Decide To Keep The Frequency Correction (ppm) => "51":
    organya22khz8bit

  3. Method 2: With A Software (Maybe More Or Less Precise):
    - If You Are On Windows Start "SDR#", But If You Are On Linux Start "gqrx"

    - Put The "Frequency Correction (ppm)" To "0" On Your Software (Search On Software Parameters...)
    [On Windows And "SDR#", Click On "Gear" Icon On Top Named "Configure Source", You Have "Frequency correction (ppm)"]
    [On Linux And "gqrx", Select "Input controls" Tab On Right, You Have "Freq. correction"]

    - Enter A Precise And Fixed Frequency That You Know (A Fixed Frequency From : FM Radio, Narrow FM, AM...)
    [If You Don't Know A Precise Fixed Frequency, Make An Internet Search To Find One]

    - Now Adjust The "Frequency Correction (ppm)" From Your Software Parameters, To Center On The Fixed Signal
    [And Find Your SDR USB Dongle "Frequency Correction (ppm)"]
