Echo - Voice Recorder & Memos

Echo Voice Recorder is a clean, offline audio recorder engineered for capturing crystal-clear voice memos, lectures, meetings, interviews, and personal notes. Built for students, journalists, creators, and business professionals, Echo combines high-fidelity sound capture with an uncompromising private architecture. Operating completely on your device with zero internet permissions, zero tracking, and zero ads, your recordings remain strictly confidential on your phone.

WHY CHOOSE ECHO AS YOUR VOICE RECORDER?
Most audio apps require cloud access, bundle background trackers, or compromise acoustic quality with harsh compression. Echo is engineered from the ground up as a private offline voice recorder:
• 100% Offline by Design: Internet permission is completely omitted from the Android manifest. Your recordings never upload to external servers or cloud accounts.
• One-Time Lifetime Ownership: No subscriptions, no monthly paywalls, and zero ads interrupting your workflow.
• High-Definition Sound: Capture clean audio using standard AAC encoding (.m4a) with sample rates up to 44.1 kHz and high bitrates up to 256 kbps.
• Battery-Efficient Engine: A native audio capture pipeline ensures extended recording sessions without battery drain.

FAST CAPTURE & POCKET-FRIENDLY VOICE RECORDER
Never miss a sudden idea, university lecture, or client interview. Echo makes starting a sound recording effortless:
• 1-Tap Quick Settings Tile: Start and pause recording directly from your notification shade without opening the app or unlocking your phone screen.
• Tactile Haptic Feedback: Distinct vibration cues confirm recording start (1 buzz) and stop (2 buzzes) so you can capture sound eyes-free in your pocket.
• Background Recording Service: Dedicated foreground service keeps capturing uninterrupted even when your screen locks or you switch apps.
• Live Waveform Visualizer: Monitor acoustic input amplitudes in real time through an ultra-responsive visual sound wave display.

STUDIO-GRADE PLAYBACK & AUDIO REVIEW
Reviewing your voice memos and lecture recordings is fast, precise, and effortless:
• Multi-Speed Audio Playback: Listen at 0.5x, 0.8x, 1.0x, 1.2x, 1.5x, or 2.0x speeds with crisp pitch correction for accelerated review.
