Long time Audacity User but first-time poster to this forum. I’ve been using Audacity to produce an Audio-Drama/Podcast for the past 5 years with no problems at all (quite an accomplishment IMO - thanks Audacity Team!). Unfortunately, my luck has run out and I’m in need of a little help.
THE PROBLEM: Audio playback in Audacity of my current project produces distorted audio. It’s a jagged, staticky, and choppy audio making playback unusable. It’s brought my production to a halt since I can’t get rid of it. Yosemite appears to be the culprit as that is the only change to my system recently. I’m stuck with Yosemite for work-related reasons.
PROBLEM DETAILS: With a lot of trial and error, I’ve actually found ways to manipulate the problem (just not eliminate it).
The distortion never occurs upon my first launch and play of an Audacity project. Everything plays just fine. However, the moment I press stop and play the project a second time, the audio playback is corrupted. When distortion appears, I can quit and relaunch Audacity for a distortion free listen… but as described, that only works once and it returns.
I noticed that the distortion will disappear only when playing certain tracks (sadly, the bulk of my tracks). I discovered that my 44100Hz tracks are the ones that experience this audio distortion. But as soon as a 48000Hz track plays (solo or overlapping), all distortion goes away. Once that 48000Hz track ends, the distortion returns. In fact, I could eliminate the distortion entirely by always having a 48000Hz track playing. I had hoped doing so and then muting the track might be a workable fix but the moment the track is muted, the distortion will return to all other audio as well.
MY SETUP: Macbook Pro 13 (2012). Intel Core i7 2.9 GHz, 8GB RAM, Yosemite 10.10.1. 150GB of free SSD disc space. I’ve experienced this problem both with Audacity 2.06 and 2.05.
I’m not the most tech-savvy person but certainly get by. I’m hoping that perhaps someone might recognize this issue and have a relatively simply fix or work around. I do have the ability to switch to Audacity on a PC if this is a Yosemite issue with no fix available. But that isn’t the most convenient or ideal solution… just a last resort so my production can resume.
Thanks in advance for any tips or suggestions.
