Meta Sound (M.Sound) User Guide & Audio DAW | MetaFile Cloud
Multi-Track Digital Audio Workstation, Web Audio Synthesis & Mastering Studio.
Overview
Meta Sound (M.Sound) is a full-featured Digital Audio Workstation (DAW) and audio mastering suite built on the Web Audio API. Engineered for podcast creators, voiceover artists, musicians, and sound designers, M.Sound allows you to arrange multiple audio stems, record microphone vocals with real-time level metering, trim waveforms non-destructively, synthesize electronic instruments, and apply studio-grade audio effects (including 3-Band Parametric EQ, Convolution Reverb, Ping-Pong Delay, and Dynamic Compressor). Export your final master in uncompressed broadcast WAV or streaming-ready MP3.
