What is a sample rate?
Sample rate is the number of times per second an audio signal is measured when converting it from analog to digital, expressed in kilohertz (kHz) or hertz (Hz). It defines the range of frequencies a digital audio file can represent - the higher the rate, the more of the original signal is preserved.
What is an example of sample rates?
CD-quality audio uses 44.1 kHz, studio recordings often run at 48 kHz or higher, while telephony and many VoIP systems use 8 kHz (narrowband) or 16 kHz (wideband) for speech.
How do sample rates work?
Higher sample rates capture more frequency detail, while lower ones reduce data size but may limit fidelity.
How does ai-coustics use sample rates?
Our models, including the Quail family, are tuned for the sample rates real-world voice AI actually uses. They run natively on telephony audio (8 kHz and 16 kHz), where most voice agents and contact centers operate, and also support higher rates like 48 kHz for broadcast and streaming workloads. Full details on supported sample rates and how to configure them are in our documentation.
