Adjusting the side tone level is critical to creating a balanced sound. If the side tone level is too high, it can overpower the rest of the audio mix and create an unbalanced sound. On the other hand, if the side tone level is too low, the speaker may not be able to hear themselves clearly. To adjust the side tone level, audio engineers use a combination of hardware and software components, including gain controls, faders, and software plugins.
Adjusting Side Tone Tone
In addition to adjusting the side tone level, audio engineers also need to consider the tone of the side tone signal. The tone of the side tone signal should be natural and balanced, with a flat frequency response. To achieve this, audio engineers use equalization (EQ) to adjust the tone of the side tone signal, boosting or cutting specific frequencies to create a balanced sound.
Using EQ to Adjust Side Tone Tone
EQ is a powerful tool for adjusting the tone of the side tone signal. By boosting or cutting specific frequencies, audio engineers can create a balanced and natural sound that allows the speaker to hear themselves clearly. Some common EQ techniques used to adjust side tone tone include:
Boosting the high-frequency range (above 5kHz) to add clarity and definition to the side tone signal
Cutting the low-frequency range (below 200Hz) to reduce rumble and mud in the side tone signal
Boosting the mid-frequency range (200Hz-5kHz) to add warmth and body to the side tone signal
Best Practices for Activating Side Tones
Activating side tones requires careful consideration of several factors, including the level, tone, and delay of the side tone signal. To ensure a balanced and natural sound, audio engineers should follow best practices for activating side tones. Some of these best practices include:
Using high-quality hardware and software components to minimize noise and distortion
Adjusting the side tone level and tone to create a balanced and natural sound
