This Monkey Shines!

Backed by the power of Sound Grinder, Sound Grinder Pro is the Studio Monkey's secret weapon. Not only does Sound Grinder Pro™ make quick work of batch processing, but also does nifty tricks like editing waveforms, extracting audio regions and Portion Control™ without leaving the application. Oh, and this Pro also batch processes with the AU and VST plugins...clever little monkey.

Asset Processing

With support for the most popular formats, you will be able to tackle your conversion operations with ease and excellent stability. Need to convert an entire hard drive into a new format keeping the entire folder hierarchy? That is no problem for Sound Grinder Pro! Even simple repetitive tasks are simplified with the use of Droplets. Create a preset, save it as a Droplet, and now, with a simple drag-n-drop, you can repeat the same process over and over again. Imagine being able to convert and upload to a server with a single step. From forced sample-rates to Portion control, you will find that you will spend more time being creative and less tie processing assets.

High Quality MP3 processing including L.A.M.E. MP3, MP3 HD, and MP3 Surround

Sound Grinder Pro includes the powerful MP3 codecs from Thomson/Fraunhofer. In addition, we include the LAME MP3 codec for those die-hard producers who demand options. With Sound Grinder Pro you can also create mono, stereo and 5.1 surround files in the MP3 format. New to version 2.0 is the ability to encode and decode your audio with the new mp3 HD format. This new format creates files that contain both a lossy and lossless track for playback compatibility. If you are looking for an archive format, mp3 HD is an excellent option matched with Sound Grinder Pro's powerful conversion options. You can learn more at

POW-r Dithering

Keep your audio assets sounding great after bit-conversion using the musical and low-noise POW-r dithering algorithm. Now available in Sound Grinder Pro and Library Monkey Pro, choose from three types of algorithms to meet your conversion needs.

Portion Control

Export user-defined portions of a file in a single batch process. Take sections of audio from the beginning, end or anywhere in-between, and apply fades based on type and duration. You can even perform an auto region and export the new regions in a single pass complete with custom naming. If you have ever needed to create demos of your work or export countless regions and loops, Portion Control is the feature you have been dreaming of.

Plug-in Processing

Batch-process your audio files through your favorite AU, VST and Monkey Tools plug-ins including the new Insert Silence and Auto-Trim plug-ins. Create a custom pipeline, preview your results before processing and create presets or Droplets to process your files with simple drag-n-drop.

Metadata Processing

Todays content producer needs the ability to edit metadata data quickly and in large batches. To meet that need, we have included several powerful metadata tools including: Ssetting specific tags to be applied to all assets on export, mapping of metadata from one tag to another, importing and viewing of MPEG 4 and ID3 artwork, and batch import using a CSV file.

Waveform Editing

With its efficient design, you will quickly find your way around the editor, saving time in your editing tasks. Work with fades, loops and markers with an intuitive interface. Edit multi-channel audio and customize the editing environment to your liking. Use the unique waveform overview to quickly navigate the audio and locate edits. Create and name regions for easy separation and exporting. Perform actions such as Normalize, Auto-Region, Auto-Trim, Apply Plugins, Change Sample Rate and much more.

Spot to DAW

Quickly search and spot your assets to Pro Tools™ or Logic Audio™ using the integrated spotting features. Import and select your assets and send them to your DAW software with a simple click. We take it one step further by providing conversion options during the spot to ensure that the assets match your session settings.
