It looks like there still are some glitches in there. In the example there are glitches and occasional beeps, like a buffer replaying the bitinbader sine once in a while. |
The previous delay code was incorrectly not utalising the whole buffer, causing glitches when incressing the delay time, due to outputting incorrect data, This was apparent when using the lfo in the Delay and Flanger plugins. This has been rectified. The read index is now offset from the write index. and the complete buffer is used in a circular fashon. Flanger - resolved issue where the lfo could create negative delay lengths

@zonkmachine Thank you for the project, That reviled a bug with short delay times, The previous code used the lfo in a way that could result in negative delay lengths, the cause of randomness. I have revised the code to eliminate this effect. |

I've tested this PR and #3521 together now and I think they should be merged. |
