This section shows how to resize wavetables in Audacity. As an example, a wavetable with a length of 256samples per single cycle waveform is converted to a length of 1024 samples.

By multiplying the speed by 0.25, the length of the waveform is increased by a factor of 4.
256 x 4 = 1024 samples

Now you can use wavetables you created in WaveEdit in Ableton Wavetable.
