Removing Echo In Audacity
How to remove recording delay on Audacity. (self.audioengineering) submitted 4 years ago by deleted So I am trying to use Audacity to record some acoustic guitar, singing, and maybe some light percussion. I use a virtual mixer called 'VB-Audio Voice Meeter' (with 2 'e's). I connect my Audio Technica AT2020 through an 'icicle', a little preamp.
Hi, Does it echo all the time until you mute the sound or when you are doing something specific or using a particular application? Were there any changes made to the computer before the issue occurred?Method 1:To remove the echo effect you may try the steps given below and check if that helps.a) Open Sound by clicking the Start button, and then clickingControl Panel. In the search box, type sound, and then click Sound.b) Click the Recording tab, clickMicrophone, and then click Properties.c) On the Listen tab uncheck the option 'Listen to this device'.d) Apply the settings and check if that helps.Method 2:If that does not help then try to disable microphone using the below given steps.a) Open Sound by clicking the Start button, and then clickingControl Panel.
In the search box, type sound, and then click Sound.b) Click the Recording tab, clickMicrophone, and then click Properties.c) Under Device usage select ‘Don’t use this device (disable)’ option and apply the settings.Check if that helps.Refer:Hope this information is helpful.Amrita MMicrosoft Answers Support EngineerVisit our and let us know what you think.
Basic approach:determine the delay. Determine the amplitude offset.invert the signal.
Apply the delay. Adjust the amplitude. Play back both audio files.any multitrack audio app is capable of this (e.g. Audacity, protools, or logic).for more complex signals, you will need to be more smart about your filtering, and ideally you would suppress the signals before they interfere (in a Skype scenario).Sounds cool, and makes a lot of sense theoretically, but I still don't really know how I should go about doing it.
I am fairly experienced with Logic, but I don't know how to determine the delay. Should i just make a copy of the file, invert it and move it around until it sounds good?Just line up the transients of the 2 signals visually to determine the delay.
Then you have to zoom way in and determine the delay to the sample to achieve the best cancellation. If it's not close, it won't cancel but add.What do you mean by amplitude offset, is that the volume difference between the original and the echo noise?Exactly. Apart from very unusual cases, the echo is going to be a different (typically lower) amplitude than the source, and you need to know this difference to cancel it best (this offset is applied to the inverted signal, btw). If the amplitude is wrong, then you will introduce the inverted signal (audibly) or, in the odd event the echo is louder than the source, reduce only part of the echo.Once the transients are aligned (to the sample) and the signal's inverted, then determine the difference in volume - if it's too high or too low, it won't cancel as much as it could.Again, that's a basic approach.

You can do a lot to improve it, depending on the signals and processors you have. In most cases, this approach will result in suppression, not elimination.
