You can use the Spectral edit multi tool. But be aware that the nominal frequency of a note only defines its pitch. All musical sounds contain overtones, at higher frequencies than the basic pitch, and it's these which largely determine the timbre of the sound. Filter out everything above 880Hz and it's not going to sound like that instrument any more!

You need an equaliser. Not any specific equaliser plugin, but any equaliser available in whatever application you choose to use. It may be a plugin, it may be built into the application. If you genuinely only want to keep frequencies below some cutoff, then you want a low-pass filter. You'll find them in the list of EQ options, or you might find a ...

A guess: What is plotted on the oscilloscope on these video is the sound wave actually coming out of the pedal. On the other hand it seems that the audio is captured using the camera (a phone maybe) as you can hear what is going on in the room (clicks). That said, it is very likely that this poor recording device, added to youtube conversion and the fact ...

In general, it's true that you can't unmix audio that has been mixed - or at least, you need a very clever program (cleverer than Audacity!) to do so. However, because you have the backing track separately, you may be able to take advantage of a processing trick involving phase inversion to get the guitar track on its own, if the backing track as recorded ...

It was recorded too loud and is clipping heavily. The top's been chopped off the waveform (see picture). The information above that 'brick wall' is lost. If there's just an occasional clipped peak, restoration software can sometimes make an intelligent guess at the lost information. But there isn't really a fix for this degree of distortion, particularly ...

Click the Play button while holding Shift. Shift + Space for short.

Because there's hardly any audible improvement past 196 kbps, so 320 is an unjustifiable ("insane") waste of disk space. Many listeners have measured this for themselves with an ABX test.

With the assumption that you have the proper equipment to record this, what you are asking can all be done with Audacity. Record your track(s), then go to File -> Save Project As. Create a folder and save the project within that folder. This will create a sub folder called "[filename]_data" and a file named "[filename].aup". To open this file in the future, ...

That waveform looks pretty typical, actually. If you were to zoom in much closer on the time axis, each "line" as you call it would become one (or more) peaks or troughs of the wave. As you probably know, the amplitude of these lobes represent the positive and negative variation in air pressure that transmits the sound. They are roughly centered around the ...

It sounds like what you want is spectral selection and editing. Spectral Selection is used to make selections that include a frequency range as well as a time range on tracks in Spectrogram view. Spectral Selection is used with special spectral editing effects to make changes to the frequency content of the selected audio. Among other purposes, spectral ...

If your characterization of "white noise" is somewhat accurate, you are out of luck. You can get various bits of noise from unstable power supply and inverters for step-up DC/DC converters and ground loops. But those will be whining or humming. Broadband noise, in contrast, is almost sure to originate from the analog circuitry of your microphone, and it ...

Start a new track. You can insert silence over the parts you don't want to keep, or mute the sections, and record the new parts in a new track. Audacity will also cut and paste across tracks, so you can build a final track with cut out pieces of the previous tracks you recorded. If you are recording to a backing track or click, you can mute each track ...

Without having listened to your track: it's not surprising at all it looks this way if this is just a bass-and-drums loop with not changes. How could it look anything but constant-peaks-amplitude, if it is a loop that literally repeats in exactly the same way? The fact that this constant amplitude is actually 0 dB (i.e. the maximum possible) is just a ...

Turns out my Audacity installation was screwed up. The low pass filter is what I wanted by it wasn't showing up, probably because I carried over an older configuration file from a previous version. So I did sudo apt purge audacity*; sudo apt install audacity and then all the regular filters were back. With low pass removing all the junk high frequencies, it ...

Thanks to endorph, I was put on the right path towards getting voices to stand out against a bunch of ambient noises. Here's what I did to clean up the audio: 1) Find a five second segment of ambient noise on the clip, highlight it, and go to Effect, Noise Reduction, create profile 2) Select the entire clip, click Effect, Repeat Noise Reduction That got ...

You're looking for an equaliser, which is an inbuilt effect in Audacity: http://manual.audacityteam.org/man/equalization.html Be aware that a voice is going to occupy more than a single frequency, and you'll need to play around to find a good setting. I find that the Preview button is very helpful here.

Removing vocals or other tracks from an already mixed and mastered file is very complex and depends on a lot of factors. There's no one size fits all answer because tracks can be mixed in all sorts of ways with many different effects. In the case of Karaoke or Guitar hero, they typically get access to the master tracks and in the case of Karaoke mix it ...

The areas you circled are caused by drawing the waveform at a lower resolution (pixels per inch) than the sound (samples per second). If the x-axis had a pixel for every sample then it would not look like it does. The patterns are not in the waveform, they are just optical illusions. Every program I have encountered draws the wave form in a similar ...

According to the information in this online Audacity manual, you can simply press Ctrl-Z straight after recording to Undo Recording. According to the manual, Ctrl-Z: undoes the last editing operation you performed to your project. You can undo as many times as you want, all the way back to when you opened the window. To undo many operations, select ...

You need to use the same software for playing the backing track and recording your performance. Otherwise you will always have synchronization issues as the two softwares are not communicating and thus are not sharing a common reference. To give an example, MIDI devices are staying synced at the same tempo by having a master device sending not less than 24 ...

A more practical approach If you are searching for a temporary solution to, let's say use the backing tracks for improvising over them without being disturbed by vocals or mid-range buzz, there's some little tricks you can do with audio material in a simple sound-editor without the need of sophisticated and expensive tools. Of course, because of the (...

Maybe the "white noise" is fan noise from your computer? If so, putting some distance between computer and microphone and letting the microphone face away from the computer (a cardioid microphone usually has a marked sensitive side, with the least sensitivity being just opposite) might help.

To shorten the clip choose selection tool (F1), select portion of the clip you want to remove and press Del key. To add silence at the end, move cursor to the end of the clip (Shift+End), select menu Generate > Silence and choose length. If you want, you can then merge the two clips, by selecting the whole track and then: Edit > Clip Boundaries > ...

What gets recorded is not primarily controlled by Audacity, but by Windows' mixer settings. The general principle is that Windows has a "Recording" channels (that's what Audacity gets) and you may or may not be able to send different sources to it. The default setting is usually the mix of all the sounds in the card. But perhaps, depending on sound card, ...

It will depend a lot on the speakers you have. Listening on my small desktop computer speakers, there's too much bass and treble and not enough mid-range. Playing with the equaliser to boost the mid-range and cut the bass and treble brought out the vocals, and made the music less harsh overall.

Just play back the song by adiocity applying this effect record the song with audiocity export it as mp3 or wave file? That's the way I would do it with finale. otherwise This should work by linking with a mini jack plug the audio-out with audio-in and recording with any wave software as audacity.
