Upload the AMR file and the converter chooses the AC3 codec / bitrate combination that matches the source profile. Lossless AC3 (WAV / FLAC / ALAC) preserves every sample exactly; lossy AC3 (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for almost all music content.

By default yes (a 48 kHz AMR produces 48 kHz AC3, a 44.1 kHz AMR produces 44.1 kHz AC3). For specific compatibility — e.g. downsampling 96 kHz studio masters to 44.1 kHz AC3 for CD burning, or upsampling 22 kHz voicemail to 44.1 kHz AC3 — the sample-rate dropdown applies high-quality SOX-style resampling.

Will the AC3 play on my car stereo / iPod / Sonos / Bluetooth speaker?
+
MP3 plays universally on every device made in the last 20 years. AAC plays on Apple, most Android, Sonos, and modern car stereos. FLAC plays on Sonos and recent Android, less well on older iPods. WAV plays on everything but the file is huge. The device-target dropdown picks a safe AC3 codec for the platform you specify.

Yes — uploaded AMR files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content. The pipeline runs on hardware we control end-to-end; no third-party services receive your file.

Same-codec re-mux (e.g. AAC inside M4A -> AAC inside MP4): 10-30 seconds. Codec change (e.g. FLAC -> MP3 or WAV -> AAC): typically 10-20% of source duration, so a 1-hour AMR -> AC3 finishes in 6-12 minutes on the standard pipeline.
