Sailer is a simple audio file player with a waveform display. Just scroll the waveform and go straight to the moment you’re looking for — more intuitive and precise than dragging a tiny seek bar. The marker feature makes it easy to repeat specific parts, perfect for transcription, music practice, language learning, and more. Supports MP3, M4A, WAV, FLAC, MP4, and other common formats. 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×. • Adjust the pitch and apply audio effects. • Add notes for future reference. *Markers and notes are saved as a sidecar file, so your original audio file remains unmodified. Pro Features (one-time purchase): • Display a spectrogram. • Export the selected region. • Export markers as TXT, CSV, or JSON. • Transcribe the selected region.
