# Audio Profile Setter Set a specific encoding profile (e.g., AAC-LC, HE-AAC, Opus voice/audio) > Canonical page: https://elysiatools.com/en/tools/audio-profile-setter - **Category:** Media - **Keywords:** audio, profile, aac, opus, mp3 ## Overview The Audio Profile Setter lets you configure and apply specific encoding profiles to audio files. Choose from formats like AAC, Opus, or MP3, and adjust settings such as bitrate, sample rate, and channels to optimize audio for various applications. ## Inputs - **Audio File** (file): Select an audio file - **Output Format** (select) - **Encoding Profile** (select) - **Target Bitrate** (select) - **Sample Rate** (select) - **Audio Channels** (select) - **Keep Metadata** (checkbox) ## When to use - When converting audio files to a specific format for compatibility with devices or platforms. - When optimizing audio quality or file size by selecting appropriate encoding profiles and bitrates. - When preparing audio for streaming, podcasts, or archival with precise encoding settings. ## How it works - Upload your audio file using the file input. - Select the desired output format and encoding profile from the dropdown menus. - Adjust additional settings like bitrate, sample rate, and channels as needed. - Process the file and download the encoded audio output. ## Use cases - Converting podcast recordings to Opus format for efficient streaming. - Encoding music files to AAC with specific bitrates for mobile devices. - Preparing audio samples with mono channels and lower sample rates for web use. ## Frequently asked questions ### What audio formats can I upload? The tool accepts common audio formats such as MP3, WAV, AAC, and others, as indicated by the audio/* file type. ### What is the difference between AAC-LC and HE-AAC profiles? AAC-LC provides standard quality, while HE-AAC is optimized for lower bitrates, making it suitable for streaming or bandwidth-limited scenarios. ### Can I preserve metadata like artist and title in the output? Yes, the 'Keep Metadata' option is enabled by default to retain tags from the original file. ### What bitrate should I choose for high-quality audio? For high quality, use 256 kbps or 320 kbps; for smaller files, 128 kbps or 160 kbps may be sufficient. ### Is there a file size limit for uploads? Yes, the maximum file size is 125,829,120 bytes (approximately 120 MB). ## 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 Set CBR](https://elysiatools.com/en/tools/audio-set-cbr): Re-encode audio using Constant Bitrate (CBR) - [WAV Compress](https://elysiatools.com/en/tools/wav-compress): Compress a WAV file by converting to MP3, AAC, OGG, or Opus - [Audio Melody Contour Extractor](https://elysiatools.com/en/tools/audio-melody-contour-extractor): Extract a dominant melody path from audio and export MIDI, note events, a pitch contour, SVG, and JSON in one ZIP. - [Audio to Multitrack MIDI (Draft)](https://elysiatools.com/en/tools/audio-to-multitrack-midi): Split a full mix into stems (drums/bass/other/vocals) and transcribe each to MIDI — a multi-track starting point for transcription - [Audio Chord Progression Detector](https://elysiatools.com/en/tools/audio-chord-progression-detector): Estimate an audio file's chord sequence locally and download CSV, JSON, SVG, and method notes in one ZIP. - [Audio Set VBR](https://elysiatools.com/en/tools/audio-set-vbr): Convert audio using Variable Bitrate (VBR) for efficient quality ## Samples - [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 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 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 - [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 ## 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.
