You can upload AMR files up to 20 MB in size. ### Can I convert AWB files as well? Yes, the converter supports both standard AMR (.amr) and Adaptive Multi-Rate Wideband (.awb) files. ### Which bitrate should I choose for voice recordings? A bitrate of 128 kbps is highly recommended for clear voice and speech audio. ### Should I choose mono or stereo channels for AMR files? Mono (1 channel) is recommended since AMR is a speech-optimized format that natively records in mono. ### Will the converter preserve my audio tags? Yes, enabling the 'Keep Metadata' option preserves available title and artist tags in the output MP3. ## Related tools - [Batch Audio Converter](https://elysiatools.com/en/tools/audio-batch-converter): Convert multiple audio files between different formats like MP3, WAV, FLAC, AAC, OGG, Opus with quality settings and batch processing - [Audio Codec Swap](https://elysiatools.com/en/tools/audio-codec-swap): Change the codec of an audio file within a chosen output format - [Audio Format Converter](https://elysiatools.com/en/tools/audio-converter): Convert audio files between different formats like MP3, WAV, FLAC, AAC, OGG with quality settings and volume adjustment - [GSM to MP3 Converter](https://elysiatools.com/en/tools/gsm-to-mp3): Convert GSM audio files to MP3 format - [MP3 to AMR Converter](https://elysiatools.com/en/tools/mp3-to-amr): Convert MP3 audio files to AMR (Adaptive Multi-Rate) format - [MP3 to GSM Converter](https://elysiatools.com/en/tools/mp3-to-gsm): Convert MP3 audio files to GSM format - [Video Audio Extract Enhanced](https://elysiatools.com/en/tools/video-audio-extract-enhanced): Extract audio from video files with advanced options - multiple formats, quality settings, and audio enhancement - [AAC to MP3 Converter](https://elysiatools.com/en/tools/aac-to-mp3): Convert AAC audio to MP3 with controllable bitrate, resampling, and channel selection ## Samples - [Copyright-Free MP3 Audio Samples](https://elysiatools.com/en/samples/mp3-samples): Collection of royalty-free audio samples for testing and development purposes including nature sounds, meditation music, and ambient audio - [Copyright-Free FLAC Audio Samples](https://elysiatools.com/en/samples/flac-samples): Lossless FLAC audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free WAV Audio Samples](https://elysiatools.com/en/samples/wav-samples): Uncompressed PCM WAV audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [AMR Narrowband Audio Sample](https://elysiatools.com/en/samples/amr-samples): AMR-NB voice audio sample for telephony playback, upload, and format conversion workflows ## Related content - [Voice Codec, PCM, and Legacy Audio Compatibility Workflows](https://elysiatools.com/en/hubs/voice-codec-pcm-compatibility): Diagnose codec and sample-format mismatches, convert AMR and GSM voice files, bridge PCM and WAV, and prepare legacy DTS or DSD assets for delivery. - [Audio Encoding and Format Conversion Tools](https://elysiatools.com/en/hubs/audio-convert): Compare audio format conversion, bitrate changes, sample-rate conversion, codec swaps, and export tools in one hub for delivery and archive workflows. - [Audio Editing and Cleanup Tools](https://elysiatools.com/en/hubs/audio-utility): Compare audio trimming, silence removal, fades, mixing, and denoise tools in one hub for podcast, voiceover, and music cleanup workflows. - [Audio Preview, Tone, and Effect Generator Tools](https://elysiatools.com/en/hubs/audio-generate): Compare audio preview generation, silence creation, ringtone building, fingerprinting, loudness reports, and effect-style audio generators in one hub.
