Sound Grinder is an advanced audio editor which converts files to the most popular audio formats.

As with most audio editors, you'll find waveform editing in Sound Grinder, perfect for quickly reviewing your tracks and making edits. You'll find converting files easy. Drag and drop your audio file onto the interface, then in the 'Convert' tab at the bottom select the right elements for file type, codec or bit depth and when you're ready press convert. Sound Grinder handles files fairly quickly.

Sound Grinder also lets you copy specific metadata from tracks like ID3, Vorbis comments or WAVE info.

I didn't really like the interface, especially the bottom section, where you set things like plugins and metadata. This part can not be resized and extended. Similarly, there is a movie preview section, but you can't select the resolution, so your videos might come out slightly distorted.

Despite some issues with the interface and the movie preview, Sound Grinder is a good audio converter.

  • * Fixed a crash issue when importing an "empty" folder - Fixed an issue where importing a folder that didn't contain any recognizable files would cause a subsequent crash.
  • * Fixed a crash issue when importing malformed AIFF and WAVE files - Added a workaround to import Region info correctly when saved with incorrect endianness.
  • * Updated Quicktime Time Reference Metadata display - Updated the Quicktime Time Reference metadata display to show a time value according to the current time units settings.

  • * Added change for empty Region Data - Added change to skip reading Region Data from WAVE files when the chunk data size is 0.
  • * Fixed an issue where certain WAVE files would not be properly imported on PPC - Fixed an endian-swap bug on PPC that would cause certain WAVE files to be imported as Quicktime files.
