Settings

The AMR audio codec supports various bit rates ranging from 4.75 to 12.2 kbit/s with toll quality speech starting at 7.4 kbit/s.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.

paf

PAF (Paris Audio File) is the native audio format of the Ensoniq PARIS (Professional Audio Recording Integrated System) digital audio workstation, developed by Ensoniq in the late 1990s. PARIS was a hardware/software DAW that earned a loyal following among recording engineers for its warm analog-like sound and reliable operation, with PAF serving as its primary working file container. The format stores uncompressed PCM audio at 16-bit or 24-bit resolution and standard professional sample rates (44.1, 48, and 96 kHz), preserving full fidelity without lossy compression. PAF uses a straightforward binary layout — a compact header followed by interleaved sample data — enabling efficient real-time read and write during recording sessions. One notable advantage is support for both big-endian and little-endian byte ordering, reflecting the PARIS system's cross-platform roots on Mac and PC. After Ensoniq's acquisition by E-mu Systems and then Creative Technology, the PARIS DAW was discontinued, but PAF files remain important for studios with archived projects in this format. Tools like SoX and libsndfile can read and convert PAF files, ensuring long-term accessibility.

amr

AMR (Adaptive Multi-Rate) is a compressed audio format optimized for speech, standardized by the European Telecommunications Standards Institute and adopted as a mandatory codec for GSM and 3G mobile networks. The codec dynamically switches between eight bit rates — from 4.75 to 12.2 kbps — depending on network conditions and background noise levels. When link quality drops, the encoder shifts to a lower rate, trading marginal clarity for transmission reliability. This adaptive mechanism is defined by the 3GPP specifications and represents one of the most widely deployed voice codecs globally, used in billions of mobile calls. The primary advantage is compression efficiency: one minute of AMR audio at 12.2 kbps occupies roughly 90 KB, practical for voice memos, voicemail, and MMS on bandwidth-constrained networks. Another benefit is built-in voice activity detection and comfort noise generation, reducing transmission during silence. While AMR is unsuitable for music due to its narrow bandwidth (300-3400 Hz), it excels at delivering intelligible speech under challenging network conditions.

Any Device

No platform restrictions. Convert your PAF audio to AMR on any operating system through a standard web browser.

Better Compatibility

PAF recordings become far more usable as AMR. The conversion unlocks very small file sizes for voice that PAF cannot provide.

No Installation

Skip the software installations. This browser-based tool handles PAF to AMR conversion entirely online, from any modern browser.

How to convert PAF to AMR

1

Select files from Computer, Google Drive, Dropbox, URL or by dragging it on the page.

2

Choose amr or any other format you need as a result (more than 200 formats supported)

3

Let the file convert and you can download your amr file right afterwards

Frequently Asked Questions

What is the benefit of converting PAF to AMR?

PAF suffers from obsolete workstation format incompatible with today's software. AMR offers standard for mobile voice messaging.

What programs can play AMR?

You can open AMR with VLC, QuickTime, AMR Player, and many Android devices natively.

Is there quality loss from PAF to AMR?

The source PAF audio has inherently low fidelity. AMR conversion preserves what is there while adding broad compatibility.

Does this converter work on mobile devices?

Absolutely. Since conversion happens in the browser, any device with internet access and a modern browser will work.

How long does PAF to AMR conversion take?

Most conversions finish within seconds. Processing time depends on recording length, but the cloud-based engine handles it quickly.

What if my PAF recording is very long?

The converter handles recordings of various lengths. For very large or numerous files, premium plans provide extended capacity.
