SOUND FORGE Pro 11 is a one-stop solution for producers who need to create and deliver master audio content for any purpose. iZotope is a premier developer of digital audio signal and effects processing plug-ins. SOUND FORGE Pro 11 includes iZotope's Mastering and Repair Suite, a collection of essential high-end processing plug-ins that you can use right away to achieve perfect masters.
In addition, SOUND FORGE Pro 11 includes two other important post-processing tools that specialize in file format integrity preservation: iZotope 64-bit SRC™ (sample rate conversion) and iZotope MBIT+ dither (bit-depth conversion).
The Mastering EQ is a six-band parametric equalizer featuring four bell filters, a high shelving filter, and a low shelving filter. It incorporates digital precision and analog modeling, as well as real-time spectrum analysis for essential visual feedback while adjusting parameters.
Precisely adjust the stereo width and focus of your master using multiband stereo imaging. Work with up to four frequency bands for independent control over stereo width by frequency. Visualize the stereo image with a powerful phase/channel meter display that highlights imaging, phase and potential cancellation problems.
Sample Rate Conversion (SRC) is a necessary process when converting material from one sample rate (such as studio-quality 192 kHz) to another (such as CD quality 44.1 kHz).
Low-pass filter quality is a critical component of any sample rate conversion process. iZotope's SRC protects against the loss of data, aliasing, noise, and unwanted ringing artifacts that appear in other implementations, and utilizes a hybrid low-pass filter along with ringing control, resulting in pristine audio quality and the highest level of control for the engineer.
The best sounding audio requires the highest sample bit depth. By truncating 24-bit or higher audio tracks to 16-bit, you are inevitably losing quality and introducing undesirable noise called quantization distortion.
Dither is the way to address quantization noise and control where it goes. SOUND FORGE Pro 11 includes iZotope MBIT+ dither. MBIT+ employs psychoacoustic methods to distribute the noise into less audible ranges, resulting in improved sound and smoother fades. iZotope MBIT+ was specifically designed for musical program material – MBIT+ models use real music and not test tones, resulting in the most musical and sonically pleasing dither available.
