| Feature | Details | |---------|---------| | | Perceptual transform coding (MDCT + Huffman) | | Sampling rates | 8 kHz – 48 kHz (typically 44.1 kHz or 48 kHz in games) | | Bitrates | 16 kbps – 320 kbps (common: 64, 128, 256 kbps) | | Channels | Mono, Stereo, 5.1 | | Low latency | Yes – designed for real-time game audio | | Looping | Built-in seamless loop support (essential for background music) | | Container | Usually raw .at9 or inside .awb (CRI Atom) or .psarc (PS4) |

The tool uses precise syntax arguments to dictate the quality, structure, and looping behaviors of the output file: Command / Flag Example / Notes -e Sets the utility to mode. at9tool.exe -e input.wav output.at9 -d Sets the utility to Decoding mode. at9tool.exe -d input.at9 output.wav -br N Specifies the bitrate in kbps. -br 144 (144kbps is standard high-quality). -fs N Specifies the sampling rate in Hz. Supports 12000, 24000, and 48000 Hz. -wholeloop Sets the entire length of the file to loop seamlessly. Highly popular for custom system backgrounds. -loop S E
