Record Audio From Any Mac OS X Application

Posted by pudge on from the mmmm-audio dept.

MrFreak writes "Have you ever wanted to grab a sound from DVD Player or record a RealMedia stream to AIFF? It's previously been impossible to do this digitally, but the folks at Rogue Amoeba have released a piece of software called Audio Hijack that allows you to record audio from any OS X application. Additionally, it can apply live audio effects to any application, so you can add an equalizer to MAME or play Quake 3 with a live echo or flanger effect."

    Total Recorder from High Criteria does this on Windows as well.

    I don't know about you, but I've been able to do this with my Sound Blaster Live! Value, always. Even with the newest version of the the Creative AudioHQ. All you do is set the recording device to Wav/Direct Sound and record with your favorite recording software. You can use the EAX or the Advanced EQ if you want.
    There is also "What U Hear". Which allows you to record everything that comes out of your speakers. So I can record my Line in, a playing mp3, and my friend on the microphone simultaneously.
    The ability to do this on the mac may be a new thing. And it's obviously a nice way around some DRM. But it's been around for a long time. At least 3 years.

    I wanted to do something similar under Linux (i.e. capturing the audio output from a quicktime player running under WINE) and a quick bout of Googling turned up dsproxy which worked very nicely, thankyou very much.

  4. vsound accomplishes the same thing under Linux by displague · · Score: 5, Informative

    We already have this in Linux (*BSD, etc.). It allows you to rip RealAudio streams, et. al.

    ~/> dpkg -p vsound
    Package: vsound
    ...
    Description: Virtual loopback sound recorder and real audio converter
    This program allows you to record the output of any standard OSS
    program (one that uses /dev/dsp for sound) without having to modify or
    recompile the program. It uses sox to convert and save the raw data
    into the desired file format and can help to convert real audio files
    to some other non-proprietary format.

    The website for vsound is here.

    If it's a .dmg file, Internet Explorer displays it like it would display a text file, same thing sometimes with tar files.


    Right-click on the link and save link target (or whatever the vernacular may be)

    You should be able to right click on the download link and select "download link to disk" or "save to disk" (not quite sure what the wording is on the windows side), It will give you a save dialog box so you can place it where you want on disk and you should be all set. Hope this helps.

    You are mistaken. There are VST effects in OS X, you will find a directory /Library/Audio/Plug-Ins/VST on any MacOS X installation.

    Audio Units are the native plugin format on OS X, like DirectX has a plugins on Windows. VST is a cross-platform plugin API written by Steinberg (and actually supported on OS X by applications like Ableton Live). Emagic is not using VST any more in it's OS X sequencer Logic, but that's probably because Emagic's owner Apple wants to push Audio Units and Emagic is a direct competitor to Steinberg.

    /dev/audio doesn't exist on OS X. CoreAudio is taking a different route than the "everything is a file" Unix approach.

  10. Re:UI vs inner workings by usr122122121 · · Score: 3, Informative
    The core issue is Apple hiding APIs to hinder customization of their OS. The fact that Audio Hijack can exist proves that low-level APIs that Apple doesn't want people seeing(at least not yet) are still accessible to adventurous hackers.
    1. The APIs are not hidden. Take a look: /System/Library/PrivateFrameworks/
    2. The article the other day was primarily about how Aqua was being kept locked up... Not the OS on the whole.
    3. Apple doesn't mind people seeing the Frameworks. They're available in the PrivateFrameworks folder. The issue, however, is that since they are private they are undocumented. Chances are that Apple just wants them to mature a bit before opening them up for everybody's use. This will prevent a bunch of developers from having their programs break when Apple modifies the framework. IMHO, some other parts of the system, like the entirety of Aqua and the private section of Quartz, will ALWAYS stay private.
