Audio is being integrated into almost every electronic device, with a much wider variety of media sources available to consumers today than ever before – all with high-fidelity audio delivery. Gone are the days of static and unwanted distortion in audio systems, and even with the move to the cloud for audio playback, streaming services offer listeners high-fidelity music. The audio space now requires more memory, more processing power, greater accuracy and better definition, yet smaller packages. With voice recognition, the ability to distinguish a vocal command from a noisy environment will require high-quality hardware embedded in the devices. Hence, key will be the dynamic range achievable and the ability to filter out any noise and interference.
This growing number of audio modules has also led to an increased need for audio test platforms that require multifunction flexibility and high-fidelity performance. Having an audio test platform that encompasses all these requirements and at high speed is invaluable.
