Silence gaps introduce pops in output file.

[jarbot]

Suddenly audio distortions have started to appear in our audiosprites files. We're not sure if it's a change to node or what but here is a fix:

(In appendSilence function line 231)

buffer.fill(null)

becomes

buffer.fill(0)

I'm running node v0.11.12 and ffmpeg 2.2.3

Previously I had ffmpeg 1.2 and the pops/cracks were still in the generated file. Upgrading ffmpeg did not resolve the issue.

Thanks for the report. For the reference, the change to Node is in nodejs/node-v0.x-archive@4b40358

The issue that caused it is now also fixed in node-master nodejs/node-v0.x-archive#8469
