What Can Cause Echoes in Your Recording?

Why there are encho in your audio recording? Reasons can be summed up in two points - the environment and the device. Echoes are sound reflections that bounce back from objects. If the object has a hard and smooth surface, it is easier to produce echoes, generally, such as walls and metal surfaces.

Now, think back on the circumstance you recorded an audio. For example, what is the room like? If the room has hard walls or a high ceiling, it can enhance the echo effect. Room acoustics explains this phenomenon.

Next, check your recording device. A microphone can pick up sound from all directions, including the source and its reflection. If you use an omnidirectional mic, the possiblity of catching echoes will increase.

Another reason that causes echoes is the speaker. If you put the speaker very close to the mic, it will lead to direct echoes. The sound amplified by the speaker is collected by the microphone again.  

Well, some recording software may create audio latency and result in an echo effect in audio during the digital signal conversion.

What Are Some Tips to Prevent Echo in Recordings?

a. Reduce room reverberations by using soft carpets and curtains. The furnishings can help with absorbing sounds. This may be the cheapest and most effective way to reduce echoes.

b. Use directional microphones and place them closer to your mouth. This type of device is designed to focus on sounds from a fixed direction and is less sensitive to sound waves from the sides.

c. Adjust the position of the speaker and microphone.
