    Bit of silence added to end of samples?

      @DanH yes I agree that this is not ideal.

      The problem is however that I'm not storing the actual length of the original sample file in the samplemap, so there is no perfect solution (and I don't want to add this as a property as this causes unnecessary noise to 99% of all samplemaps).

      What I can do is to use the initial sample end as it is stored in the samplemap to be used as maximum length:

      <samplemap ID="supershort" RRGroupAmount="1.0" MicPositions=";" CrossfadeGamma="1.0"
                 SaveMode="2">
        <sample Root="60" LoKey="60" HiKey="60" LoVel="0" HiVel="127" RRGroup="1"
                FileName="{PROJECT_FOLDER}supershort.wav" Duplicate="1" SampleEnd="19678"
                SampleRate="44100.0" LoopXFade="0" SampleStart="0"
                MonolithOffset="0" MonolithLength="20480"/>
      </samplemap>
      

      Here the SampleEnd property is the actual sample length value, while the MonolithLength is padded to a multiple of 4096. I cannot change this because the HLAC reader always reads chunks of 4096 samples (and if it plays a few samples of silence it won't change anything).

      Currently the waveform renderer gets it's max range by looking at the full range that is available to the HLAC reader which is the zero padded length. I can add a function at the initialisation stage that checks the sample end value and then overrides the full length for the waveform preview while leaving the audio rendering side as it is, but this means that if you change the sample end & resave the samplemap, the area beyond that new end is forever gonzo (unless you revert the samplemap back to non-monolith or manually edit the SampleEnd property to the max value).

      I still think that's a better solution as the HLAC conversion will also truncate the sample range thats encoded into the monolith so there are not too many use cases where you might want to edit the sample range after the HLAC conversion. Note that if you change the sample properties using scripting later on this will not affect the displayed range as it was already initialised correctly with the sample map value.

          @DanH Alright, I've pushed this, let me know if that works for you.

            @Christoph-Hart some weirdness going on.... It's looks just as I want it but only for one sample map πŸ˜† After that the AudioWaveform tile goes blank. Setting the index to -1 doesn't show sample played, although maybe that's just s symptom of the same underlying issue.

            So I open the project, load a sample map, it shows the waveform as I want it (thanks!) but then that's it for waveforms....

            EDIT - seems to affect only some of the sample maps. I'll see if I can figure out what's going on....

            • Could be something to do with loop end points getting moved outside of the sample range. If that's the case hopefully I can reconfigure them and crack on but I'll see if something is going wrong which might affect others.

              @Christoph-Hart so..... my loop points (if I set any) aren't getting saved in my sample maps. When the map loads some of the maps seem to set the loop end point to the monolith length amount which is outside the scope of the new waveform tile πŸ˜†

              I've got to run out so will look a little harder later. Not 100% sure why the loop info isn't getting saved though... Or why the loop end defaults to monolith length as I'm sure it used to default to sample length...

                @DanH I think if the loop end is the sample end it will remove the property because thatβ€˜s the default but if you can reproduce it with a certain samplemap I can take a look.

                  @Christoph-Hart as far as I can make out if I reset the loop point to something within the range, disable looping, save the map, quit hise, re-open and load the map then it should work. Enabling looping again can then make it not work. I've got one map that refuses to display a waveform in loop mode. Shall I dm?

                      Alright, should be fixed now - samplemaps with loop points indeed caused the padded size to not being set correctly but that was an easy fix.
