SPL De-Esser 9629 Problems and Solutions
some common issues and solutions for the SPL De-Esser 9629, as described by experts:
Issue: The de-esser is removing too much sibilance. Solution: Try reducing the Threshold setting. This will tell the de-esser to only remove sibilance that is above a certain level. You can also try increasing the Ratio setting. This will make the de-esser more aggressive in removing sibilance.
Issue: The de-esser is not removing enough sibilance. Solution: Try increasing the Threshold setting. This will tell the de-esser to remove sibilance that is below a certain level. You can also try decreasing the Ratio setting. This will make the de-esser less aggressive in removing sibilance.
Issue: The de-esser is creating a harsh sound. Solution: Try decreasing the Amount setting. This will tell the de-esser to only remove a certain amount of sibilance. You can also try increasing the Release time. This will give the de-esser more time to recover from removing sibilance, which can help to prevent a harsh sound.
Issue: The de-esser is not working on certain frequencies. Solution: Try using the Frequency Response graph to see which frequencies are being affected by the de-esser. You can then adjust the Threshold and Ratio settings to target those frequencies.
Here are some additional tips from experts:
- Use a high-quality microphone to minimize sibilance in the first place.
- Place the microphone slightly away from the mouth to reduce plosives.
- Use a pop filter to further reduce plosives.
- Experiment with different settings on the SPL De-Esser 9629 to find what works best for your voice.
