Apr 24, 2025High-End Microphone Capsule SNR ChangesFrom 2005 to 2015, the Signal-to-Noise Ratio (SNR) of the most advanced microphone capsules in the mass-market consumer electronics increased from below 60dB to around 65dB. Today, -
Apr 24, 2025Importance of Microphone Capsule Performance for Noise Cancellation AlgorithmsA microphone capsule with high AOP can help speech recognition systems in noisy environments, where the speech signal itself may not be loud, but other interferences are present. F -
Apr 24, 2025Importance of Microphone Capsule Performance in Speech RecognitionFor systems where the captured sound is used by algorithms, the goals for sound quality may differ from those intended for the human ear. As long as the microphone signal is optimi -
Apr 17, 2025Importance of Microphone Capsule Acoustic Overload Point (AOP) in RecordingJust like SNR, AOP is a crucial factor for audio/video quality. There are many smartphone videos online, filmed at popular/rock concerts, where the audio is severely distorted and -
Apr 17, 2025Importance of Microphone Capsule Signal-to-Noise Ratio (SNR) in RecordingThe purpose of audio/video recording is to capture sound from a source and reproduce it at the output of the microphone system. The microphone and its SNR (Signal-to-Noise Ratio) a -
Apr 17, 2025Microphone Capsule Acoustic Overload Point (AOP)All real-world audio transducers are nonlinear systems and inherently produce distortion. Distortion is typically measured by Total Harmonic Distortion (THD), or THD + N if includi -
Apr 10, 2025Microphone Capsule Signal-to-Noise Ratio (SNR)The noise in a microphone capsule's output refers to any signal other than the intended input source-typically unwanted elements that degrade the overall audio signal quality. -
