Mossca
Minimal. Fast. Built for great sound.
Mossca is a high-quality Mac music player built for your personal music collection.
Launch in 1 second. Start listening. Behind the simplicity is a powerful audio engine.
From local music and personal music servers to built-in audio and external DACs, Mossca brings playback, audio processing, and output together in one clear audio path.
No complicated setup. Open Mossca, choose your music, and press play.
A powerful audio engine. Simple control.
Mossca Audio Engine provides high-quality playback and processing for different sources, sample rates, and output devices:
• High-quality PCM playback
• Exclusive Output
• High-quality SRC and upsampling
• Real-time PCM → DSD modulation
• Native DSD playback
• DSD over DoP
• EQ processing
• Headphone profiles
Keep the defaults and just listen, or adjust processing to suit your music, headphones, DAC, and preferences.
PCM → DSD
Mossca can modulate PCM music to DSD in real time and output it to a supported external DAC.
From PCM through real-time DSD modulation to DoP and DAC output, Mossca creates a complete processing path for a different approach to digital-to-analog conversion.
It is not simply a format change, but a different approach to sound reproduction.
Multiple DSD rates are supported, with output selected according to your device’s capabilities.
Native DSD and external DACs
Optimized for high-resolution music and external DACs:
• DSD (DSF / DFF)
• DSD64 – DSD512
• DoP output
• High-resolution PCM
Mossca selects the appropriate playback path based on the audio format, DAC, and output conditions. If the target DSD rate exceeds your DAC’s capabilities, it can automatically select a supported rate.
Exclusive Output
With supported devices, Mossca can establish a more direct audio path:
• Exclusive access to the audio device
• Avoid unnecessary system mixing
• Reduce unnecessary system resampling
• Match output sample rate to the playback path
Headphone tuning
Mossca provides headphone profiles and EQ processing for different headphones.
Connect your headphones, select a profile, and tuning becomes part of the Mossca Audio Engine playback path.
All your music. One player.
Play music from:
• Mac and external storage
