ai-coustics vs Denoise

ai-coustics provides audio-processing tools for Voice AI systems, preparing incoming sound for speech recognition and other downstream tasks. Its Quail models enhance speech and can reduce word error rate by as much as 30%; Quail Voice Focus suppresses competing voices to isolate the foreground speaker. Tyto predicts whether audio may cause downstream failures and returns a score with the cause. A voice activity detection model is designed for complex real-world environments without a separate denoising tool. The SDK runs enhancement, voice activity detection, and audio analysis on CPU within the customer’s application. The company says on-device processing has sub-40 ms latency, and audio processed by the SDK remains on the customer’s infrastructure. Integration options include Python, Node.js, C, C++, Rust, and WebAssembly, with guidance for LiveKit and Pipecat. A free SDK trial is offered through the Developer Platform, and paid plans start at $135 a month billed annually. Startup includes 100,000 minutes per month; Pro is $360 a month billed annually, Business is $540 a month billed annually, and Enterprise starts at $2,000 a month. The company’s own infrastructure runs in AWS eu-central-1 in Frankfurt, Germany.

Denoise is an audio cleanup app for Android and iOS that uses an on-device neural network to reduce wind, traffic, hiss, hum, and crowd noise in voice memos, interviews, and videos. Processing runs locally, including in airplane mode, and a one-minute clip typically takes 5–10 seconds. Users can import recordings from Voice Memos, Photos, Files, or an app share sheet; supported inputs include MP4, M4A, MP3, and WAV. The free plan lets users import, process, and hear a before-and-after preview, but saving and export require Pro. Pro can export M4A, MP3, or WAV, replace audio inside a video, restore detail in clipped, muffled, or distant recordings, and separate vocals from instrumental tracks on-device. Audio tools include a 5-band EQ with presets and automatic LUFS normalization. There is no file-length limit, including for recordings up to a three-hour lecture. Routes Software says recordings are neither uploaded nor stored, and the app has no user accounts. Google Firebase collects anonymous usage analytics and crash and diagnostic reports. Pro costs $2.99 a month or $14.99, paid once for lifetime access.
