Cassette Music Player: Sunlit

Sunlit Cassette turns your phone into a cassette deck for the music you already own.

Wow and flutter, tape saturation, hiss. Mechanical transport sounds sampled one by one from an '80s deck. And a VFD spectrum analyzer glowing in that unmistakable cyan.

An offline music player for your local files — MP3, FLAC and more — with a full 32-bit float effects chain and hi-res support.


■ TAPE EFFECTS

• Wow and flutter, with separate speed and depth
• Tape speed (±15%, with optional pitch lock)
• Azimuth drift, saturation, hiss noise
• Low-pass and high-pass filters

■ AM RADIO EFFECT

• AM modulation for that narrow, distant radio sound
• Interference mode
• Mono and stereo switching

■ VINTAGE EQUALIZER

• Ten equalizers, from a 3-band retro unit to a full 31-band
• Left and right channels can be set independently (±12 dB)
• Bass boost, loudness, 3D virtualizer, reverb
• All running on a custom DSP engine in 32-bit float

■ TWO WAYS TO CONTROL

Emo and Pro modes on every effect — tape, equalizer and AM radio.

• Emo — a few sliders move several parameters together. Instant results
• Pro — every parameter on its own. The more you refine, the closer to your ideal sound

■ MECHANICAL SOUNDS

Sampled one at a time from a stylish '80s deck.

• The mechanical clunk of play, stop and pause
• Opening the case, lifting the tape out

■ HI-RES AUDIO (Android 10 and above; device support required)

• FLAC, MP3, AAC, WAV and more
• Hi-res tracks show their sample rate on a badge

■ VFD SPECTRUM ANALYZER

A display built to look like a real vacuum fluorescent tube.

• Track and artist names glow with a soft bloom around their edges
• Five bloom patterns — Night Room, Hi Energy, Brick Road, Tear Up, Star Burst — plus off
• Honeycomb grid overlay in three densities, or off
• Three spectrum scales — follow Nyquist (hi-res shows its top octave), fixed 20 kHz ISO, or a retro gauge
• Overlay the spectrum with the track name, or show either on its own

■ ALSO INCLUDED

• Save and recall your sound settings as presets
• Browse albums as cassettes on a shelf, and change the wallpaper
• Lyrics display, read from tags embedded in your files
• 10-second skip
• Press and hold fast forward or rewind for the whirring tape sound
• Wow that responds to movement — the sound wavers as you walk or run, like a portable deck with no anti-shock
