Unwanted echo and reverb on audio recordings occur when sound reflects off walls, floors and ceilings with enough strength to be picked up by the microphone. Completely removing these effects from a recording is impossible, but freeware audio editor Audacity has some tools that may help you reduce the effects of these sound reflections, the most effective usually being a noise gate, which allows you to control echo, reverb and other noise between segments of important audio.
Download and install the noise gate plug-in provided through the Audacity website, if you do not see 'Noise Gate' listed under 'Effect' on the toolbar. You may need to restart Audacity after installing the plug-in before it appears on the menu.
Open the audio file with the echo you wish to reduce in Audacity. Click 'Effect' on the toolbar and select 'Noise Gate' from the list. The noise gate window is an offline effect, meaning that it will process your audio before you play it back to hear the effect.
Set the controls of noise gate to remove echo and other unwanted noise content. Start with 'Level reduction' at -100, 'Gate threshold' at 30 and 'Attack/Decay' at 75. Level reduction tells the gate how much to reduce unwanted audio. The gate threshold sets the volume level at which the gate starts to reduce sounds and the attack and decay setting affects how quickly the gate process starts and stops. Click 'OK' to start the process.
Play the result of the noise gate process. Evaluate the effect of those settings. If there is no change to the echo, increase the threshold setting until the echo occurring after important audio is sufficiently reduced. Reduce the threshold setting if the noise gate cuts off important audio. This process may take several attempts. Click 'Edit' from the toolbar, then 'Undo' to restore your audio to its original state between attempts.
Bluestacks taking forever to load. Adjust the level reduction and attack/decay settings to make the noise gate effect more natural, after you find an effective threshold level. Increasing level reduction adds some echo, but you can control what level. Increasing the attack and decay time smooths out how the gate effect begins and ends. Slower settings make the effect less noticeable.
Tips
You may be able to use an equalizer to 'tune' a resonant echo out of a recording, but this is not a technique that applies to all cases.
Warnings
Work on copies of your original file to prevent loss of data if you accidentally over-process your audio.

There are two types of echo in an audio recording. Natural echoes and approximated echoes. The former occurs as a consequence of the acoustics in which the audio was captured. The latter is a deliberate audio effect added to create the illusion of space and depth. Some echoes are desirable and add character to a sound, other echoes are not desirable and can make an audio recording sound muddy. Fortunately, you can remove an echo from your audio using the tools in your audio software program.
Removing Natural Echo
Open the program that you used to record the audio, such as Logic or Pro Tools. If you recorded the audio without a computer and now wish to edit the audio with a computer, open your preferred audio production program and click “File.” Click “Import” and select the audio from which you wish to remove the echo. Since the echo is part of the audio as it was captured on the recording, you need to manipulate the sonic characteristics of the recording.
Open the “Noise Gate” application. Its location in the menu varies according to the program, but noise gates are typically located under “Effects” or “Plug Ins” in the “Gating and Limiting” or “Dynamics” sub-menu. A noise gate is a signal limiter. It mutes any signal under a pre-selected threshold.
Click the “S” icon on the audio track that has the unwanted echo. This solos the audio so everything else is muted.
Hit “Play” and adjust the threshold parameter on the noise gate interface. This interface governs how strong the audio signal is before the gate allows it to pass. Since the echo will be a lower level than the original sound, set the threshold so that it sits between the level of the sound and the echo. This way the original sound will have a sufficiently strong signal to breach the gate threshold, while the echo is too weak and will be muted.
Removing Echo Effects
Open the program on which you recorded the audio.
Click on the track with the unwanted echo. By clicking on the track, you bring up all associated effects and parameters. These typically appear in a side-bar on the left.
Examine the display to determine which virtual effect is creating the echo. It is likely to be one of “Reverb,” “Delay” or “Tape Echo.” Reverb is a more subtle effect, similar to an echo but distinct from it in that only the ambiance is audible, rather than a recreation of the original sound. Delay and tape echo effects are more obvious.
Open each effect interface by clicking on the effect icon in the sidebar. Turn the effect off by clicking the “Bypass” button.
Play the audio back. If the echo is still there, bypass the next effect. Once you bypass the offending echo source, click “Bypass” once again on each of the effects that you tried. This brings them back into operation and returns the audio to its previous form, minus the echo.
Tips
Record audio in an acoustically dead environment. It's easier to add an echo effect than to remove a natural echo.

How To Eliminate Echo In Audition
Archived
Complete beginner to Audition, I usually just shoot video and then edit in Premiere.
I recorded some audio in a large room with flat walls, which produced a ton of echo in the recording; you can really hear the subject's voice bouncing off the walls.
To try and fix this, I looked up a few tutorials and combined some techniques. Here's what I did:
- Captured the noise print of the ambient room tone
- Used noise reduction to get rid of that room tone
- Used parametric equalizer to remove some annoying frequencies. Basically swiped around with a peak until I found a frequency that sounded strange, then reduced it to -15db. After lowering a few frequencies, the quality of the voice sounded much better, but it had almost no effect on the echo.
- Used another parametric equalizer to enrich the voice, I guess? Very slightly increased the highs & lows and decreased the middle frequencies. This made the voice sound much more crisp and less muffled.
- Added a single-band compressor. I guess this evened out the volume of the voice? It didn't make a huge difference, but still improved it a little.
There was a tutorial that recommended you lower the middle frequencies through the dynamics processing tool. I tried this, but it seemed to just lower the volume of the voice and had little to no effect on echo.
How To Reduce Echo In Adobe Audition
Overall, the voice now sounds much better, it's much more pleasant to listen to. However there's still a ton of echo; after the subject says something, you can hear their voice bounce around the room.
Is there anything else I could do to reduce this (without external plug-ins)? Any feedback is greatly appreciated, thanks!

So I'm editing a short film right now, and location sound from one scene is pretty bad. I am a video editor, with some basic knowledge of sound design, but I'm not an audio expert.
The sound from the location was all sorts of messed up - no slate, no timecode, bad acoustics in the room, bad background noise, and recorded quietly. Just getting the audio synced in the first place was a small miracle. I know I'm not going to get it perfect, but I've managed to get it to a much better spot even with just some preliminary tinkering.
I boosted the gain in Premiere (20 db) to get it to an audible level, which brought the BG noise up considerably. Now I'm reducing that in Audition using the Noise Reduction effect, and it's actually working pretty well. However, this effect can leave the audio sounding a little hollow. The raw audio already sounds like it was recorded in a tin can, with some slight echo/reverb, so now there's no BG noise but the remaining audio is very tinny.
I've heard there are presets that can help with this, but is there any way to do it with the stock Audtion toolset?
Again, I know I'm not going to get it perfect, but any kind of help or advice would be greatly appreciated. Just trying to reduce echo/reverb/tinny sound.
The following 340 users say Thank You to for this post: 340 users say Thank You to for this post.,. Eso auto loot addon.
I can upload examples of the raw audio if needed.
Thanks!
EDIT: Here is a link to the audio I'm working with. First sample is completely raw, just boosted to be audible. Second sample is after Noise Reduction in Audition.
