Sailer: Repeat & Speed Changer

Sailer is a simple audio file player with waveform display. 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.

Features:

• Seek by scrolling the waveform.
• Pinch-to-zoom for more precision.
• Use markers to bookmark specific positions*.
• Move a marker by long-pressing and dragging left or right.
• Double-tap (or two-finger tap) between markers to play only that section (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.
