Export pattern as WAV file

[grampalak]

Hydrogen version * : 1.0.1
Operating system + version: Windows 8.1 Pro
Audio driver + version: Realtek integrated

---

While Hydrogen will export a song as a wav file, the inability to do this with a selected pattern is disappointing. Although the Project Menu dropdown seems to indicate that this is going to be possible (Export pattern as...), no format other than as a .h2 pattern is available. I'd like to suggest this capability as a new feature request. Otherwise, I love what Hydrogen allows me to do!
Thanks for your hard work. :-)

As a suggestion, adding some info regarding Interpolation future (on export screen) could be useful.

I'm not sure I understand "interpolation future". Do you mind adding some detail? Thanks for your input.

Should there be a "loopable" option?

There are different use cases for exporting a pattern as a wave:

• one-shot, plays once through (eg. for a break or for teaching a pattern)
• looping the same pattern over and over

Using the existing export methods, by default a pattern won't be loopable (depending on what's in it). Consider something like a cymbal crash on a pickup beat like:

BD: |O---O---O---O---|
CC: |---------------X|

To make the pattern loopable, you'd want the start of the pattern to contain the sustain of the crash; but not when it'd be used as a one-shot.

During export, there is an interpolation feature. Explanation of it is shared before in a webpage reference. But I think a quick info could be useful for this feature in export screen. Just a simple suggestion, don't mind. =)

Maybe a toggle button to include or not the very last sustain? I mean working in both modes one-shot and looping
After all one-shot mode is just a loop with 1 only repetition, so there could be a QSpinBox in the export dialog to select nRepetitions.

I agree. The interpolation is used (at least) when samples are resampled at different rate frequency for the "doppler like" note pitch shift.
