# Audio Bit Depth Reducer Reduce the bit depth of an audio file (e.g., 24-bit to 16-bit) > Canonical page: https://elysiatools.com/en/tools/audio-bit-depth-reducer - **Category:** Media - **Keywords:** audio, bit depth, s16, s24, s32 ## Overview The Audio Bit Depth Reducer converts audio files to a lower bit depth, such as from 24-bit to 16-bit, helping reduce file size or meet specific format requirements while preserving essential audio quality. ## Inputs - **Audio File** (file): Select audio (WAV/FLAC/MP3/OGG/OPUS) - **Target Bit Depth** (select) - **Keep Metadata** (checkbox) ## When to use - When you need to reduce audio file size for efficient storage or streaming. - When preparing audio for devices or platforms that only support lower bit depths. - When standardizing audio files to a consistent bit depth for a project or workflow. ## How it works - Upload your audio file in a supported format like WAV, FLAC, MP3, OGG, or OPUS. - Select the target bit depth from options: 16-bit, 24-bit, or 32-bit. - Optionally, enable the 'Keep Metadata' checkbox to preserve tags such as artist and title. - Process the file and download the converted audio with the new bit depth. ## Use cases - Reducing file size for podcast distribution to meet hosting platform limits. - Converting high-resolution audio for compatibility with standard audio players or car systems. - Preparing audio samples for game development or mobile apps to optimize memory usage. ## Frequently asked questions ### What audio formats are supported? The tool supports WAV, FLAC, MP3, OGG, and OPUS files up to 125 MB in size. ### Will reducing bit depth affect audio quality? Reducing bit depth can lower dynamic range, but for most listening scenarios, the difference is minimal, especially when converting from higher to standard bit depths. ### Can I keep the original metadata? Yes, enable the 'Keep Metadata' option to retain information like artist, album, and title in the converted file. ### What is the maximum file size allowed? Audio files must be under 125 MB to be processed by this tool. ### Does this tool support batch processing? No, currently it processes one audio file at a time for conversion. ## Related tools - [Audio Codec Swap](https://elysiatools.com/en/tools/audio-codec-swap): Change the codec of an audio file within a chosen output format - [Audio Resample](https://elysiatools.com/en/tools/audio-resample): Change the sample rate of an audio file (e.g., 44.1kHz to 22.05kHz) - [Audio Change Sample Format](https://elysiatools.com/en/tools/audio-change-sample-format): Change audio sample format/bit depth (e.g., s16, s24, s32, fltp) - [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 - [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 Channel Resample](https://elysiatools.com/en/tools/audio-channel-resample): Change the number of channels (mono/stereo) while keeping the same format - [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. ## 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 Raw PCM Audio Samples](https://elysiatools.com/en/samples/pcm-samples): Raw PCM s16le audio samples featuring nature ambience and relaxing music for waveform, playback, and conversion workflows ## Related content - [Make Legacy Voice and Audio Files Playable Again](https://elysiatools.com/en/hubs/voice-codec-pcm-compatibility): Diagnose codec, container, sample-rate, bit-depth, and channel mismatches, then choose a bounded conversion path for a target player or processing chain. - [Convert Audio Without Guessing the Codec or Delivery Settings](https://elysiatools.com/en/hubs/audio-convert): Inspect the source, choose one deliberate conversion path, change only destination-required parameters, and verify the delivered audio file.
