What MTransformer does
The plugin changes frequencies directly, so any frequency can be moved to any other frequency, a process that differs from ordinary pitch shifting. Each frequency level can be transformed on its own, which lets loud and quiet parts of a sound be handled separately. MTransformer is listed as VST3, VST2, AU and AAX for Windows and macOS, with native support for Apple Silicon.
Modulation is part of the design: any parameter can be driven by an LFO, an audio level follower or an envelope, so the sound does not stay static. Standard MeldaProduction features include 16x upsampling and M/S processing.
Key features
- Frequency transformation. Frequencies can be shifted to any other frequency, with each level transformed separately, which is the core of the plugin.
- Level-based processing. Each frequency is handled according to its own level, so loud and quiet frequencies in the material are treated differently.
- Modulation sources. Parameters can be modulated from an LFO, an audio level follower or an envelope.
- Upsampling and M/S. The standard MeldaProduction set includes 16x upsampling and mid/side processing.
Compatibility
Formats are VST3, VST2, AU and AAX for Windows and macOS. The minimum system is macOS 10.14 or Windows 8, and native Apple Silicon support is listed. A trial version is available.
