How can i get two different Waveforms?
in you function "admissonToolStripMenuItem_Click" you have a small typo...
you have:
_admissonFileName = this.openFileDialog1.FileName;
_admissonHelper = new BassHelper(_originalFileName, this, this.pictureBox2);
change to: (otherwise you load the first audio again!!
_admissonFileName = this.openFileDialog1.FileName;
_admissonHelper = new BassHelper(_admissonFileName, this, this.pictureBox2);
