Sailer: Audio File Player
Listen offline with waveform
Free · Designed for iPad. Not verified for macOS.
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*.
• 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.
• Transcribe the selected section.
• Export the selected section.
*Markers and notes are saved as a sidecar file, so your original audio file remains unmodified.
