# M4A to AAC Converter Convert M4A (MPEG-4 Audio) files to raw AAC format with quality and channel controls > Canonical page: https://elysiatools.com/en/tools/m4a-to-aac - **Category:** Media - **Keywords:** m4a, aac, audio, converter, transcode, mpeg4 ## Overview The M4A to AAC Converter allows you to easily extract raw AAC audio streams from M4A containers or transcode them with precise control over bitrate, sample rate, and audio channels. Whether you need to optimize audio files for specific hardware players or reduce file sizes while preserving metadata, this tool provides a fast, browser-based solution without requiring software installation. ## Inputs - **Audio File** (file): Upload an M4A file to convert to AAC - **Bitrate (kbps)** (select): Choose target bitrate for AAC output - **Sample Rate** (select): Output sample rate - **Audio Channels** (select): Select output channel count - **Keep Metadata (when available)** (checkbox): Preserve title/artist tags when possible ## When to use - When you need to extract or transcode M4A audio files into raw AAC format for compatibility with legacy media players or embedded systems. - When you want to compress M4A files by adjusting the bitrate, sample rate, or downmixing stereo audio to mono. - When you need to prepare audio assets for streaming platforms that strictly require raw AAC streams instead of MP4/M4A containers. ## How it works - Upload your M4A audio file (up to 50 MB) using the file selector. - Configure your output preferences, including target bitrate (from 64 kbps to 320 kbps), sample rate, and channel layout. - Choose whether to preserve existing metadata tags like title and artist, then click convert to generate and download your new AAC file. ## Use cases - Optimizing voice recordings by converting stereo M4A files to mono AAC at 64 kbps to save storage space. - Preparing high-quality music tracks for hardware players by transcoding M4A files to 320 kbps AAC at 48 kHz. - Stripping container overhead from M4A files to produce raw AAC streams for custom game engines or web players. ## Frequently asked questions ### What is the difference between M4A and AAC? M4A is a file container that typically holds AAC-encoded audio, whereas raw AAC is the bare audio stream without the MPEG-4 container wrapper. ### Can I convert multiple M4A files at once? No, this tool currently supports converting one M4A file at a time with a maximum file size of 50 MB. ### Will I lose audio quality during the conversion? Transcoding between lossy formats can cause minor quality loss, but you can minimize this by selecting a high bitrate like 256 kbps or 320 kbps. ### Does this converter preserve my audio tags and metadata? Yes, if you enable the 'Keep Metadata' option, the tool will attempt to preserve tags like title and artist in the output file. ### What sample rates are supported? You can keep the original sample rate automatically, or manually select 44.1 kHz, 48 kHz, or 96 kHz. ## 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 - [Audio Splicer](https://elysiatools.com/en/tools/audio-splicer): Splice multiple audio files into one single audio file with customizable output format - [Audio Change Bitrate](https://elysiatools.com/en/tools/audio-change-bitrate): Re-encode audio to a new bitrate while keeping the same format - [Audio Cutter](https://elysiatools.com/en/tools/audio-cutter): Cut and extract audio clips from audio files with precise time selection - [M4A to MP3 Converter](https://elysiatools.com/en/tools/m4a-to-mp3): Convert M4A audio (AAC/ALAC) to MP3 with bitrate, resampling, and channel controls - [Audio Channel Resample](https://elysiatools.com/en/tools/audio-channel-resample): Change the number of channels (mono/stereo) while keeping the same format ## Samples - [Copyright-Free M4A Audio Samples](https://elysiatools.com/en/samples/m4a-samples): Apple iTunes compatible M4A audio samples with AAC encoding, optimized for quality and file size balance - [Copyright-Free AAC Audio Samples](https://elysiatools.com/en/samples/aac-samples): High-quality AAC encoded audio samples for testing and development, featuring nature sounds and meditation music with excellent compression - [M3U8 Audio Samples](https://elysiatools.com/en/samples/m3u8-audio-samples): HLS audio playlists for streaming tests - [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 - [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. - [Audio Measurement and Inspection Tools](https://elysiatools.com/en/hubs/audio-analyze): Compare loudness, dynamic range, peak, BPM, key detection, spectral inspection, and metadata review tools in one hub for audio analysis.
