Speaker Booster - Ampcrank

Volume maxed out and still hard to hear? Ampcrank is an audio-boosting player: import your music, podcasts, recordings, and voice messages, then make them louder and clearer with real volume gain and a full equalizer. VOLUME BOOST - 0 to +24 dB digital gain — turn the knob and hear the difference instantly - Built-in limiter keeps audio clean and distortion-free even at maximum boost - Live level meter and spectrum animation show the boost at work EQUALIZER - Vocal Booster: brings muffled, unclear speech into focus - Bass Boost: deeper, punchier low end - Podcast / Voice Memo: tuned for recordings and voice messages - 10-band manual EQ (31 Hz–16 kHz) with savable custom presets A COMPLETE LOCAL PLAYER - Import MP3, WAV, M4A, FLAC, and AAC from the Files app or iCloud Drive - Extract the audio track from MP4 videos - Receive audio files shared from other apps via the system share sheet - Background playback with Lock Screen and Control Center controls CLEAN AND SIMPLE - No account required; your audio files stay on your device and are never uploaded HOW IT WORKS Ampcrank enhances audio through digital signal processing (gain + EQ + limiting) applied to files played inside the app. It does not raise your iPhone speaker's hardware volume limit, and it does not amplify other apps, ringtones, or phone calls.
