When making a conversation in outdoor and recording, or shooting a motion using a microphone, the microphone picks up the wind sound which makes difficulty to hear the voice. Attaching a windshield sponge to a microphone could be a solution to avoid such wind noise, but it cannot be applied to a smartphone. As the wind sound hits the microphone has many low frequency components, it may be effective to suppress the low frequency components with a high-pass filter. However, this method suppresses the low frequency components of the sound even when the wind is not blowing.
TMC has developed a software IP that detects the wind noise in real time and instantly reduces the wind noise only when the noise is detected.
|Sampling Frequency||8kHz, 16kHz, 24kHz, 32kHz, 48kHz|
|Input / Output Data Format||16-bit linear PCM (monaural or stereo)|
|Strength of Wind Noise Suppression||Adjustable in 4 steps (Max. suppression of approx. 20 dB)|
