<![CDATA[Loud click artifact when using ReleaseStart with looping enabled]]>I'm working on my first HISE library and have encountered a weird consistent issue, where there is a loud click artifact during sample playback whenever I use looping and ReleaseStart on the same sample.

The click only happens when I have both looping and ReleaseStart set.
Scenarios:

  • Loop ON + ReleaseStart SET, note held: Sample loops cleanly with no click at
    the loop transition. However, after the loop restarts, a loud click appears at
    exactly (I think) the duration it would take to play from the ReleaseStart position
    to SampleEnd
  • Loop ON + ReleaseStart SET, note released: Transition from loop to release
    offset is clean. A loud click occurs the moment SampleEnd is reached.
  • Loop ON - ReleaseStart 0: Sample just loops and slowly fades out based on DefaultEnvelope Release time
  • Loop OFF + ReleaseStart SET: No issues, even with envelope release time set to max. Playback reaches sample end with no click

This behaviour occured both on the standalone version and the latest stable built from source version.
My sample was exported with a 10ms linear fadeout, and even before that I knew it was at least -80dB at SampleEnd.

Hise: 4.9.2

I just rebuilt it on my MacBook with the snippet and the downloaded sample on Hise standalone. Single sampler, single sample, loop region and ReleaseStart outside of the loop region towards the end of the sample.

Tried changing all ReleaseStart settings, but none have an effect.
Release Fade Time 0-10000
Fade Gama 0-1
Gain Matching: All three modes
Peak Smoothing 0-1
UseAscendingZeroCrossing: Yes No.

I still consistently get a click/popping sound.

Also realised I did the snippet format wrong.
How is it supposed to be?
