Mac Audio problems?
I don't know if it's just me, but the audio normalization on the mac OS is kinda terrible - an almost game breaking experience. The mid range and low range is good, but it seems as if the high end (treble) of the audio files are getting cut off and I can hear crackling at the end of sentences or with the monk's static electricity aura. It feels like a signal to noise ratio problem, or a low bitrate/conversion problem.

Running latest version of mavericks,
Ivy Bridge i7 @2.9 GHz

It's odd, as it impoves with my analog amplifier (i attached it to high impedence headphones), but on speakers or TV connection (3.5mm input/output) I can still hear the crackling (even though i'm using the same audio out connection).

[update, Jan 6, 2013]: after more playing.. I realized the analog amplifier also has this problem. I also tried it with a USB DAC, (Fiio E07K (Andes) and the E17 (i believe)), they both work and actually improve the audio, so I don't have any crackling or normalization issues. However, the sound output is extremely low. Due to the low volume (i almost have to turn my computer speakers up all the way, then the USB DAC to 2/3 max volume to adequately hear it, with a 6dB gain, 12 dB gain doesn't have enough steps for me to control audio properly), I think the main audio problem is due to an inherent boost/gain that the game applies when porting out speakers or the audio port in the Mac. By bypassing that port, and using a DAC, there's no more audio problems. Someone can try a BT headset and a USB speaker set to test out that theory (i'll try a BT headset in a few days).

[update Feb 3, 2014]: no updates for the time being, busy with Chinese New Years and life. USB DAC to audio solution works well. Most likely a bit-rate conversion issue on the mac. GL, and I'll repost an update once i test out other solutions.

I'll try another digital amplifier to see if it makes a difference via USB out versus anolog headphone amp to see if there's a difference (my computer DAC/software codec/or w/e). Otherwise, it's not a bad game. I just... wish the audio was clearer instead of 128 bit.

[belated update June 22, 2014]: So, analog to analog doesn't help the situation. I honestly just think it's the sound files themselves. My USB DAC works because there's less noise than an analog solution and I can adjust the gain accordingly. If I turn up the USB DAC, I will again notice the crap audio, so using a USB DAC only mitigates the problem, doesn't fix it. Good luck - post if you guys find a solution.

I have this problem too. Will post a video up soon.

"i have the same issue" -.- That's not helping anyone. Please provide also information about your OS.

However Steam discussions isn't the place to get technical support. Either visit the official forums or try to contact Trendy like requested.

Hey I went to the Audio MIDI Setup (go to applications -> Utilities -> Audio MIDI Setup), then played around with the frequency at 'Built-in output'. Try 48000.0 Hz. If can't, go higher. I was successful at 88200 Hz. All static was gone! Hope this helps.

Awesome that someone posts a solution, well done :)

Just wanted to add a data point - the solution didn't fix the problem entirely for me, but it helped! I'm playing on a Macbook Air though.
