• Record your own podcast and interviews, edit out the mistakes, uhs, and umms, and encode in MP3 or AAC for your podcast feed

Recording and editing:
• Natively edit in 32-bit floating-point for high precision with no need to worry about clipping
• Handles any sample rate: playback and recording limited only to hardware capabilities

• Low latency audio
• Timer recording
• Automatic starting and stopping of recording based on audio volume level thresholds
• Smooth zooming in and out of the audio waveform
• Zoom in all the way in to individual sample level and make edits with sample-accuracy
• Ruler units for film (24 fps and feet-frames) and television (25/30 fps)
• Marker system for placing cue points or chapter markers
• Save each chapter as a separate file or track for importing into iTunes
• Grid system for aligning edits to whole packet sizes, BPM, or other units

• 3-Band EQ: adjust the bass, mids, and treble
• 10-Band EQ: adjust 10 different frequencies from 40 Hz to 20.5 kHz
• Graphic Equalizer: create your own parametric EQ envelope

• Low Pass Filter: remove all frequencies above the threshold

Core Audio plug-in effects (Audio Units):
• Use both Apple-supplied and 3rd party Audio Unit effects
• AUMatrixReverb: full control over sound reflections, with several presets
• AUDynamicsProcessor: control over dynamics, including compression and expansion
• AUMultibandCompressor: dynamics control on different frequency bands
