Audiotrack sample playback error

Description

When playing back some (not all) samples from an Audiotrack device, the playback will have a loud click or pop right at the start of the sample. This pop happens only on the first playback but disappears on subsequent playbacks (the start of the sample will be played back correctly). Unfortunately, the click or pop will appear on the published mix-down.

Note

This bug existed in Flash too and it was possible to get rid of the click/pop at publish time by playing back the arrangement until the start of the sample at least once. The published mix-down would then be correct. Unfortunately, this workaround doesn't work in Next and the published mix-down always has the pop.

Steps to reproduce

Start a new arrangement and open the sample panel.

Type "vibraphone" on the search field.

Drag the sample "vibraphone - no motor - c3" to the desktop and connect the Audiotrack to the Master Output.

Before starting playback, open the timeline and drag the audio region one or two bars forward in time.

Start playback. The app generates a loud pop when reaching the start of the sample.

Stop and start playback again. The sample plays back correctly without the pop.

If you'd publish the project, the mix-down would have the pop at the start of the sample even after a correct playback.

Does this only happen when the sample plays solo, or does adding a background noise/pad make the popping sound go away?

In my experience, the pop happens anyway, regardless of what else is playing. If you look at my latest track https://www.audiotool.com/track/36ejx6vi/, you can even see the huge initial spike at the very beginning of the waveform at the top of the page. Thanks for taking a look into this. :)

I currently cannot reproduce your steps. But I also don't hear that sound in you published track so maybe someone else is more qualified ;)

Can you try that with a silent/soft sample before the vibraphone. Does this also produce a click on the first playback?
Another test/workaround: does it help to automate the volume (simply a constant value at the start of the track)
