BitPerfect App Reviews

Make icon programs for black themes OSx. Thanks.

Previously it worked. Now is not working.

:) Program became more sustainable. Than you for your program.

con itunes 11 va in crash,sempre.

I’m an experienced musician and electrical engineer and Audio buff but not by any means an Audio fool. I just bought a sweet pair of Fostex Headphones ($400) from MassDrop and realized well I need a fancy DAC to up the game of my 2011 MBP. Once I got that ($120 but very nice unit from OriGen) I realized the proper way to drive the DAC is by letting the source drive the sample rate. And that is all I really needed BitPerfect to do. I use BP 3.1 with the latest iTunes and now am collecting some Higer Res files. Do High Res files sound better or are they just remastered perfectly? ha. Not totally sure. But the tracks I do have do sound great, that I’m sure of. Does iTunes have bad sound? You have to be an Audio-fool to say yes unless you are doing some processing (advanced EQ) sample rate conversion or perhaps volume and even then I doubt iTunes is all that bad. For me, iTunes is set on 100% volume and I’m sure it is already Bit-Perfect, I’ve read enough and know enough about engineering and sound. Bitperfect does keep the system sounds out of my music and switch my DAC to the correct sample rate flawlessly. I avoid upsampling and all that other BS and keep it simple. Buff, not fool. Setup sounds great! BP works as advertised. For $10 bucks, BitPerfect is just that. Perfect. All those other fancy players are a waist of money uless you are doing real room EQ compensation or something fancy. Is the iTunes interface a love hate relationship? Yes, but I still prefer it. And Bit perfect rounds out the key feature I needed with is simply DAC sample rate switching. BTW When using Apple music, BP does not controll your DAC, your Midi setting does.

Because BitPerfect is playing your audio instead of iTunes, your equalizer settings are completely ignored. Just something to be aware of if you care. In my experience, messing with the EQ for 5 minutes makes a much bigger difference than a nice DAC or exactly matching the source and output bitrates. It works as advertised (in my limited testing), though.

Ive not encountered the concern regarding software equalization, by including two "dvx Audio" 131s 31-band 1/3 octave hardware equalizers (one per channel) right after the nuForce uDAC (Digital to Analog Converter that Ive ben using with the Audirvana App) and before the external amplifier. BitPerfect sounds, well .. perfect !

As noted in title Im using a Musical Fidelity USB Dac… Bitperfect sounds definitively better allowing me to output 24/96khz to the DAC and then out to my Digital Crossover & Digital Room Equalizer. Keeping everything at 24/96 from start to finish is a huge key for my setup due to the hardware digital processors. Thank you Bitperfect! One thing Id like to see, and I know its not "BitPerfect" is an equalizer. Maybe 10-15 band parametric EQ. The reason is that it would be great for adjusting the sound of specific headphones while still making use of the up sampling and the higher sample rate support to synergize with my external DAC.

Im running a pair of B&W MM-1 active desktop speakers with my iMac w/OSX 10.6.8. These speakers connect via USB, are self-powered, and have a built-in 44.8kHz/16-bit D/A converter. Using BitBerfect with iTunes 10.7, the app does what it claims to do, but there is a bug. If I power down the speakers at any point, and then later turn them back on, BitPerfect hangs and will not play music unless I restart the computer. Trying to access the program from the menu bar icon, all I get is a spinning beach ball. The computers Sound Preferences and Audio MIDI setup are set correctly. I dont leave the speakers powered up all the time, so this is annoying. The developer encourages users to contact them with issues, but there is no email address or phone number listed on their support blogsite.

Absolutely seamless playback here - Bitperfect on my digital audio workstation brings simple iTunes up to the sound quality of other sophisticated sound/music applications. Sound quality improvements: The sound is clearly deeper - there is more fine detail epecially within the quieter elements of the signals. This gives the sonic illusion of more space - a wider sound stage - one of the hallmarks of recording fidelity. For the price, this is a great improvement! My equipment: Im using iTunes 11 on a mac pro (24 Gig RAM) running mountain lion (10.8.2). My DAC is good but not leading edge. It is built into an Edirol MIDI USB interface, which sends a clean balanced signal to Mackie balanced monitors and headphones. Integer mode is N/A. I run the DAC at 44.1kHz/24 bits to leave USB bandwidth for MIDI I/O and monitoring. Source files: anywhere from old MP3s up to huge 96kHz/24 bit HD tracks. They all sound better to varying degrees. Suggestions: 1) add a link to BitPerfect support in the menu; 2) maybe add a handy interface to AudioUnit plug-ins and rate their inherent quality/destructiveness? (examples - a crossover for multi-amping or mix/delay/filter functions for more complex distribution systems) Bottom line: There is no more convenient and flexible music interface for daily use than iTunes so it is a shame that Apple doesnt give users the options to accomplish what BitPerfect does. But for a small fee, BitPerfect corrects Apples oversight.

Wow... wow... well executed, transparent app! I have finally woken up from my PureMusic user experience nightmare. I am using my MacBook Pro with an AQ DragonFly (mobile) or a NuForce Icon HDP+u192s (home) and its great to be able to use the track skip (RW/FF), play/pause and volume controls again on the keyboard. Oh, yeah, and I can scrub the track progress back-and-forth and easily re-listen to my favorite riffs; you know, the way iTunes used to work before I started using Pure Music. You know what else I love? Playing back gapless tracks without waiting for the whole album to load into memory. And, no more wading through menus and restarting the app to change DACs between my portable and desktop rigs. Bitperfect seems to use only a fraction of the RAM previously used by PureMusic, looking at the ActivityMonitor; I love this feature, because Photoshop and Illustrator are busy using the rest of the 8GB I have on my system. It was always great to see designers I work with laugh when I show them the PureMusic UI, but I am happy to no longer be looking at it myself - someone was on acid when they designed those visuals.

The newest release is an obvioulsly untested software. It locks up frequently and just doesnt work. I used to like this software, but will now use a real program like Amarra

Unfortunately BitPerfect did not work as advertised. When selected to run the dac at 192khz sampling rate, it was able to do so. However, when selecting my music folder in the BitPerfect software, the software bugged out, and changed my computer settings to limit output to the dac at 44khz. I had to quit the BitPerfect software and enter the Audio MIDI Setup.app in OSX and manually change the bitrate sent to the dac back to 192 khz. Each time I opened the BitPerfect software it would change my computers output to 44khz. Ideally, I would like a refund for the software since it has in no way performed what it has said to do. For users reading this, your Mac will read a usb DAC. Go to Audio MIDI Setup.app in your spotlight search and choose the highest bit rate at which you want your computer to output to the DAC. BitPerfect is unnecessary, in my case, to play high bit rate music - Maybe that is the case for you as well.

Have been generally happy with BitPerfect, but I Just updated from the previous verison and now all my songs just loop through the first 3 seconds over and over again. Great. Does anyone test these updates? Problem goes away as soon as I disable BitPerfect. I run iTunes 10.7 under OSX 10.6.8.

output may be bitperfect, but only a few seconds at a time. Ya see, it syncs up its own playback with itunes play bar. For some reason, itunes playbar lags when bitperfect is running. Bitperfect sees the bar being behind, then sets itself to match. Bitperfect blames Apple. Apple says iTunes if fine. And my wallet? $10 lighter and nothing to show for it. I ended up buying Decibel, which doesnt skip.

Its quite simple to setup, except it does not remember which DAC is priotized. The sound is a step-up than without it. Im too lazy to setup anything other than the iTunes library I already have. Hopefully, the developer will keep adding features, I dont mind a price hike or a separate upgraded app. You need to charge for each version, otherwise, there is no money to collect. Im all for supporting sustainable app ecosystem.

The sound is great, when it works. But after a couple songs I get screeching distortion. No fix was made after a year, and now the latest release wont load my library.

This solution is so simple, but makes such a profound sonic difference to all the music I play. If your using a quality DAC then this is your solution.

I’ve been using this app for several months and the developer has been active with updates as needed and was compatible with Mavericks before it was released. Now I can finally use the integer mode with my DAC! Totally transparent with iTunes this is a must have so your mac can handle multiple bit/sample rates on the fly.

If you take the time to configure this app for your setup, it really does make your music shine. Even the onboard audio of my 2009 Macbook woke right up. I’ve done plenty of A -> B testing, and the difference is significant. If you’re using a DAC (headphone or otherwise), and/or you’re playing high resolution audio (or lossless ripped CDs), you should have BitPerfect if you’re using iTunes to play those files. Playing my music through my Sennheiser HD 650 has been a real joy after installing this.
