Tune Up Audio

[Takako Dito]

TUNES Arena earphones were engineered to experience studio music at its purest form. Equipped with dual-driver speakers to deliver professional acoustic tuning to provide an unparalleled audio experience.

Hi! I just gave up a recording session trying to record some electrical guitars on a track I'm working on. Something wierd happened with the audio that I've never encountered before. The guitar tracks I record sometimes get recorded in an uneven pitch lower than the actual sound. It also got stretched a little and out of sync with the rest of the band/metronome. I plugged the guitar in my amp, and recorded the sound through an Roede USB mic. I've tried unplugging and plugging in the mic to reset the audio device, and restarted Logic X, but it doesn't seem to help. Sometimes it records the audio properly, sometimes it is recorded a quarter step down and out of tune and time. Is it a 44 100 vs 48 000 Hz sampling problem? Why is it coming and going? The tracks already recorded in an earlier session are not affected and are played back correctly. It's really annoying heaving to delete and redo the guitar parts several times and loosing good takes to a bug.

You will have to Monitor through the Rode. Set the sampling rate in Logic's preferences, and/or in the Rode's configuration software (if it has any?). If it is a sampling rate problem this should cure it.

I recorded again today, the error happened just once. The sample rate in Logic is set to 44.1, tried changing it to 48 and back to 41.1 just to "reset" the sample rate. Haven't had any more problems after that, but that might just be coincidental.

My interface is the SE X1 USB (not Roede as i brainfartedly claimed in my first post), where i use the mic as input and my Macbooks headphone-port/internal soundcard as an output, and I've been using this set-up for over a year and never encountered this problem before. There is no configuration software for the mic, just plug-and-play.

If the weirdness becomes more of a problem again i will try your suggestions, but it would be a pain to have to use the mic for monitoring as it often is on the floor recording the amp, but i guess i could buy an extension-jack if i have to.

Legendary for its vocal enhancing and creative applications, the Auto-Tune effect revolutionized modern vocal production. A UA exclusive, the Auto-Tune Realtime X plug-in gives you the ultimate low-latency Auto-Tune solution, in the studio or onstage.

Auto-Tune Realtime X plug-in gives you the clearest user interface yet, with workflow enhancements like dark/light mode, easy Undo, and a Mix control to quickly add Auto-Tune effects without setting up effects sends.

Terrible Business Model and Disappointing Experience

I am extremely disappointed with this plugin. I bought it just a few days ago, and now suddenly there's an update that costs an additional 108 - 327 euros. This is a really bad business model. Ripping off customers like this is absolutely unacceptable. I will definitely not buy from you again and cannot recommend it to anyone.

This is one of those plugins that you think won't need it, until you need it, and it works fantastic I can fix any out-of-tune vocal with my current DAW, but it has a cost in sound that sometimes is annoying. Now with Realtime X I can fix at tracking in a very accurate way, which save you a lot of work at editing and mixing.

Like other one-star reviewers, Antares and UA took away my previous version of realtime, too. I preferred that version... and now they're asking $149 for me to get it back?? Screw that. This would be a five-star review if I simply had access to the old version again.

Unbelievable, I have to pay for an upgrade 2 weeks after I purchased the outdated version. Very disappointed that UA continues with this tactic and am not surprised that people are turning away from supporting this legendary company.

When recording a simple 3 track backing track (bass, drums, guitar) I have noticed that, sometimes, if I play it back within audacity, it sounds perfectly in tune and I can play along to it fine in real time. However, when exporting the track to a wav file and playing over that in real time (outside Audacity), it is very very slightly flat. I am wondering what might cause this.

Hmm, never thought about it in terms of speed before. The exported tracks I have noticed this on have been more like 99% speed if that was the factor altering the pitch! It is very subtle and admittingly I am a bit of a perfectionist when it comes to pitch accuracy!

While it is true that converting from 24 bit to 16 bit may reduce the sound quality very very slightly, there is no way that such a conversion in itself could account for a change in pitch. At most it will add a tiny (virtually inaudible) amount of distortion or noise.

Have you checked the pitch before exporting?
Have you tried importing the exported file back into Audacity?
Is there a difference in length between the original audio project (before exporting) and the length of the file if you import it back into Audacity?

The ability to transpose and fine-tune audio adds a lot of flexibility when working with audio files. For instance, if you have a keyboard loop collection in which every loop is in the key of C, being able to transpose these loops to any other key opens up many possibilities.

To transpose any audio Event, select it and open the Inspector by pressing [F4] on the keyboard or clicking on the Inspector button above the Track Column. Then enter a value in the Transpose field, from -24 to +24 semitones.

Any number of Events can be selected and transposed or tuned simultaneously, but note that this change is not relative to the current setting of each Event. All selected Events are transposed or tuned to the same chosen value.

I recently wanted to measure the belt tension on my Prusa MINIs. I know there's a printable device that can be used to measure belt tension, but I don't have PET filament handy so I looked for an alternative approach. I found this forum post from several years ago on using an audio frequency spectrogram app (on a smartphone) to measure the belt tension. However, I didn't see any values reported for the MINI, the values were all over the place, and the topic is closed so I could reply.

I have three MINIs, each with fewer than 500 hours of printing logged and all printing normally. So I'm starting a new topic here to report the frequencies that I measured in case it's a useful reference to anyone else.

I used the Android app "Spectroid" to take the measurements. When you pluck the belt, you'll see a variety of frequencies/bands appear and then disappear once the belt stops vibrating. You'll want to measure the lowest/minimum frequency - the rest are harmonics or multiples of the fundamental frequency. You should also pluck the belt multiple times so you make sure you're getting consistent results each time. For the X-axis belt, I pushed the extruder all the way to the right (closest to the Z-axis); the normal home position doesn't push the extruder all the way. For the Y-axis belt, I pushed the print bed all the way to the front of the printer (toward the end with the control/display). For both belts, I plucked the top belt, just to be consistent; the top and bottom belts do have slightly different frequencies because their free lengths (the length that can freely vibrate) differ.

I've attached an example screenshot of the spectrogram from plucking the Y-axis belt. I've dragged the green measurement lines over the fundamental/minimum frequency at around 79 Hz. Note that there is a noise band just to the left - that is not related at all to the plucking of the belt because it's "always on" whether the belt is vibrating or not. The smaller, diminishing peaks to the right of the fundamental frequency are the higher frequency harmonics- these can be ignored.

Given the consistency among the values and the fact that all my printers are working properly, I think that these values are within an acceptable range. I'll use this as a reference in the future to adjust the tension of any belts that are too loose or tight.

Lol thanks @jsw for making that connection ? I suppose an instrument tuner might work too if one doesn't have access to a smartphone though I haven't tried it. Here's a reference on bass note frequencies for anyone who's curious.

Though I do love the analogy, I'll note that when plucking the axis belts on a Prusa I find it extremely difficult to discern any pitch (and I do sing and play piano and guitar so it's not that I can't just discern pitch more generally). It's more of a fluttering noise than a pure tone. I mention it just in case anyone thinks that they might be able to tune the belt tension by ear. Perhaps there are folks out there more skilled in this than I. Fortunately, the spectrogram app is sensitive enough to pick up the frequency, and with added precision.

Note that Prusa has come up with an app to measure the sound and indicate if the belt tension is correct, but only for the MK4 and XL. The Mini has been left out, even though it appears that it is possible to do so as this thread indicates.

The Audio Test Bench provides a graphical interface through which you can develop, debug, test, and tune your audio plugins in real time. You can interact with properties of your audio plugins using associated parameter UI controls. See audioPluginParameter for more information.

audioTestBench(pluginPath) opens the Audio Test Bench for pluginPath, where pluginPath is the location of an external plugin. Use the full path to specify the audio plugin you want to host. If the plugin is located in the current folder, specify it by its name.

When writing to an audio file, select Overwrite existing file to overwrite the specified file if it already exists. Otherwise, Audio Test Bench creates new audio files with an underscore and a number appended to the specified file name.

The Audio Test Bench has the same functionality as generateAudioPlugin and audioPluginConfig for generating audio plugin binaries. You can choose from multiple plugin binary formats, and you can specify the coder configuration for deep learning and code replacement libraries.
