Sailer: Audio File Player

Sailer is a simple audio file player with a waveform display. The interactive waveform view allows precise and intuitive seeking, even in long-form audio such as radio broadcasts, audiobooks, and lectures. The marker feature makes it easy to repeat specific parts, perfect for language learning, transcription, music practice, and more.

Supports MP3, M4A, M4B, WAV, FLAC, MP4, MOV, and more.

Features:

• Seek by scrolling the waveform. • Pinch-to-zoom for more precision. • Use markers to bookmark specific positions*. • Double-tap (or two-finger tap) between markers to play only that region (loop supported). • Adjust playback speed from 0.25× to 4.0×. • Add notes for future reference.

*Markers and notes are saved as a sidecar file, so your original audio file remains unmodified.

Advanced Features:

• Transcribe the selected region. • Export the selected region. • Display a spectrogram.
