These filters can help enhance the sound quality of the audio track by adjusting the frequency levels, reducing background noise, and controlling the dynamics. Additionally, you can also use audio plugins or effects within the software to further customize and filter the audio tracks to achieve the desired sound. **

It may also be helpful to work with a professional audio engineer or speech therapist who has experience in addressing speech impediments in audio recordings. **

Generally, an external filter is quieter than an internal filter. This is because external filters are usually placed outside the aquarium, reducing the noise level inside the tank.
