Projects are all out of time!

[Gothboy]

I'm experiencing a most perplexing problem. For some reason my Luna projects....or at least the one I'm working on now....are out of time and not keeping up with the 120.00bpm of the current project. The audio files I've rendered are slower and according to my metronome are at 104bpm. When I try to change the bpm in the count window I get no flashing cursor and I have to type into a second window to change it. I've re-installed Luna and restarted the computer but still no fix. Need help on this one!

Could it be that the audiofiles you're using are not at the same samplerate than the ASIO device.

For example: if you load an audiofile of 44.1 kHz into LUNA, but LUNA'a audio engine is running at 48 kHz, then the audio file will be played a bit quicker, at a bit higher pitch because of the difference in samplerate.

Solution is to resample the audio file to the same samplerate as you're working in.

Resampling can be done with e.g. Audacity. Best to save the resampled audiofile with a new name, e.g. "oldname-48khz.wav".

Does this help?

Thanks for the quick reply! Well, it's the opposite of that really. The .wav files are playing back at a lower pitch and slower tempo in Luna but play at the right pitch and tempo in another player. Friday night everything was working fine.
Yesterday I recorded a live stream of a concert off the internet straight into Luna the bpm was kept at 120 and it rendered a nice recording of the show. I checked the recording against the live stream and both were at the same pitch and speed.....that was the last thing I did with Luna....now everythings fouled.

The example of the higher pitch, faster tempo was an example.

Lower pitch, slower tempo is just the same indication: there is a difference in samplerate between the audio file and the asio device you're using in luna.

Solution given above.

Alternatively, you could try to set your asio sound device to the same samplerate as the audio file of course.

To see the samplerate of a wave file, right-click on it in Windows, choose "Properties->Summary" and there it is

[muzycian]

Note: the first solution is the best one, imho.

Thus resample the wave file to the same samplerate than your asio device is using.

As said, resampling can be done with Audacity: http://audacity.sourceforge.net

...you're right. The sample rate of my audio files for this project is at 48K. The concert was recorded at 44 and my other projects are at 44. I don't know how this happened but I'll do the conversion in Audacity.
Luna is still acting up though. Why it presents a second bpm type-in window is odd and when I try to open another project in Luna it's not giving me a proper drive hierarchy.

[Gothboy]

I have Audacity and I'm in there right now but here's the odd thing...The 48k files are playing back at the right tempo in Audacity, so when I change the sample rate to 44.1 they play back at the slower speed. Then when I export them and open again in Luna they're still slow.....so I'm missing something important here. These are 48K, 32-bit float files.

You need to resample them, not just save at a different sample rate. I don't see how to do that in Audacity.

Luna is still acting up though. Why it presents a second bpm type-in window is odd and when I try to open another project in Luna it's not giving me a proper drive hierarchy.

Clicking the tempo allows to edit it via left/right mouse buttons, and via the mouse wheel.

Double-clicking that field again allows you to input the value via the numeric keypad.

I agree that it would be better if step 1 is eliminated.

May be in a future LUNA version!

Resampling in Audacity can be done via the "Change Speed" effect.

In this case, use factor 8.84354% <=> ((48/44.1)*100)-100

Cheers!

Or, as I just found:
1) Set default sample rate to destination sample rate (edit->preferences->quality)
2) Add a new stereo track (Tracks->Add New->Stereo v1.3 | Project->New Stereo Track v1.2)
3) Import the track with the "bad" sample rate (File->Import v1.3 | Project->Import Audio v1.2)
4) Export as a 2-track WAV file (just "File->Export As Wav" in v1.2; in v1.3: File->Export, set to two tracks, link the project tracks to the output tracks, L->L, R->R)

More long-winded but it saves doing the maths...

[Gothboy]

Can this be done with version 1.2.3? I decided to use the more stable older version?

Any way you can go through this step by step....I tried it and it does not work for me.....how do you enter the math?

I've updated the instructions.

You don't enter the maths. You enter the number in "Percentage Change".

[Gothboy]

I entered the number 8.4354 in the percentage change area and it was still exported at the slower rate at 48 despite me deliberately setting the "set Rate" to 44.1. So I still don't get this?
See what's happening is you can change the sample rate in Audacity, you can also change the speed of the file...but you can't change the sample rate of the file so it's different in Luna....at least I can't! When I open the file in Luna it's playing at a slow speed and going to the properties of the wav file show it to still be at 48k. I've got a major headache at this point.
