background echo

I have an audio downloaded but when playing it, the recording has a lot of background echo, probably from recording in a small closed room. Is there a filter to help reduce the hollow effect for the recording. Any help appreciated.

Is there a filter to help reduce the hollow effect for the recording.

If it is echoes or room reverb, you can be the biggest hero in the world if you find a filter that can get rid of it. Everybody trying to home-record podcasts, instructions, manuals and audiobooks will beat a path to your door.

I might beat one.

The modern convention of bare, wooden floors and bare walls and ceiling qualifies as an Aggressively Hostile Recording Environment by sound people. There’s no way to rescue a recording done that way.

You should contact the original producer and complain.


Thanks, problem is…it’s my recording. Recorded a video for church and did not factor in room factors. Thanks for the reply.

Occasionally Noise Reduction can help if you take some of the echo between words as the noise profile. It could make it sound weird.

Or try “Isolate Center” in Vocal Reduction and Isolation.

You may need paid for effects to make a reasonable job. Search for “deverb” online.

Suggesting strongly an internet audio show created by someone else.

We can only go with what you tell us.

ACX/AudioBook has videos on how to produce audiobook (and broadcast) sound work.Their work is a little over the top, but perfectly valid. Many people are producing good sound products from an overstuffed closet.

Also, the Transom people (National Public Radio) have good ideas and explanations.

It almost always boils down to Echoes and Reverberation, Environment Noise (Room Tone) and way down at the bottom of the list, Microphone. Everybody wants to reverse the list. “What microphone should I buy…?”

There was a recent radio theatrical presentation about a presenter who takes a small, portable sound recorder into a closet with a quilt and routinely cranks out quality voice tracks. So it doesn’t have to be a multi-thousand dollar sound studio, contractors and city permits.

I see an illustration in today’s Washington Post where a Senator is being interviewed by people holding small, personal recorders. No microphones in sight.

Just for future reference… The amount of echo coming from all-directions that sounds normal (or that sounds great with music) in a church or concert hall usually sounds terrible when coming from a pair of speakers is a small room.

The solution is to get the mics close to the speaker/performer for more direct sound and less reflected “room sound”.

Sometimes pros use additional mics to multi-track record the room sound. Then, they can mix-in the room sound to taste in post-production.
