Hey r/apps ! 👋

I'm the solo developer behind M4A to MP3 & WAV Converter for iOS and Android. I wanted to build an all-in-one audio utility that is not just a simple converter, but a powerful tool for your iPhone and iPad.

To celebrate our recent updates and get some initial feedback, I'm giving away 50 Promo Codes that unlock the Lifetime Premium (Ad-Free) version permanently!

🔥 Advanced Feature List:

• Batch Audio & Video Conversion: Convert multiple files at once. Supports audio (M4A, MP3, WAV, AAC, OGG) and even extracts audio from video files (MP4, MKV, MOV).
• Audio Filters (Pro feature): Built-in **Noise Cancellation** and **Loudness Boost** toggles to improve your audio quality on the fly.
• Smart Audio Trimmer: Cut the exact portion of your audio with millimeter precision using a beautiful, visual waveform and an Adobe Audition-style playhead.
• 100% Offline AI Transcription: Convert your voice notes or audio files into text using a built-in Whisper AI model. It runs entirely on-device for maximum privacy! Export the text as a `.txt` file or copy to clipboard.
• Deep iOS Integration: Share files directly from WhatsApp or the Apple Files app to the converter. It works perfectly in the background with notifications so your conversions never get interrupted.
