Converter Based The ATS-2 offers an excellent value in audio analyzers. Its converter-based architecture keeps the cost down while offering a wide range of features at high levels of performance. Converter-based audio analyzers generate and analyze signals in the digital domain and use analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) for analog input and output.
