Bitrate- vejledning
- 64 kbps - Lav kvalitet. Stemme/tale kun, meget små filer. Velegnet til podcasts, hvor båndbredden er begrænset.
- 128 kbps - Standard kvalitet. Acceptabel for casual lytter. God balance af kvalitet og filstørrelse.
- 192 kbps - Høj kvalitet. Markant forbedring over 128k. God til musikbiblioteker.
- 256 kbps - Meget høj kvalitet. Near-transparent for de fleste lyttere og udstyr.
- 320 kbps - Maksimal MP3-kvalitet. Stort set umulig at skelne fra tabsfri.
Which Format Should I Use?
- MP3 - Universal compatibility, sharing online, portable devices
- WAV - Professional audio editing, mastering, studio work
- FLAC - Lossless archiving with smaller files than WAV
- OGG - Open-source projects, game engines (Unity, Godot)
- AAC/M4A - Apple ecosystem, iTunes, better quality than MP3 at same bitrate
- AIFF - Mac-native lossless, Logic Pro, GarageBand
- OPUS - Best lossy codec for low bitrate, VoIP, Discord, streaming
Hvordan lydkonvertering virker
Convert between any audio format in three easy steps. Our server-side FFmpeg pipeline handles all the heavy lifting.
Upload Your Files
Drag and drop one or more audio files onto the upload area, or click Browse to select files from your device. Our converter automatically detects the input format and displays file information including duration, bitrate, sample rate, and channels. Batch processing is fully supported for converting multiple files simultaneously.
Vælg outputindstillinger
Vælg dit ønskede output format fra de ni tilgængelige muligheder. Fintune kvalitet med bitrate kontrol (64-320 kbps for tabende formater), sampling rate udvælgelse (22.05 kHz til 48 kHz), og kanal konfiguration (holde original, konvertere til mono, eller konvertere til stereo). Lossless formater som WAV og FLAC ignorere bitrate indstilling, da de bevarer fuld kvalitet.
Download din lyd
Click Convert and your files are processed on our servers in seconds. Preview the converted audio with the built-in player to verify quality before downloading. For batch conversions, download all files as a single ZIP archive. All uploaded files are automatically deleted within one hour for your privacy.
Audio Conversion Use Cases
Audio format conversion is essential across music production, content creation, software development, and everyday media management.
Device Compatibility
Convert audio files to formats compatible with your phone, car stereo, smart speaker, or media player. Not every device supports every format, so converting to universally compatible MP3 or AAC ensures your music plays everywhere without compatibility issues.
File Size Reduction
Convert large WAV or AIFF files to compressed formats like MP3, OGG, or OPUS to dramatically reduce file size. A 50MB WAV file becomes a 5MB MP3 at 192 kbps with minimal perceptible quality loss, saving storage space and bandwidth for uploading and sharing.
Professional Audio Production
Convert compressed audio to lossless WAV or AIFF for editing in DAWs like Ableton, FL Studio, and Logic Pro. Ensure you work with the highest quality source material for mixing and mastering. Convert final masters to multiple delivery formats for distribution.
App & Game Development
Game developers and app builders convert audio assets to optimized formats for their engines. OGG for Unity and Godot, OPUS for web applications and WebRTC, WAV for sound design tools. Batch convert entire asset libraries to the correct format for your platform.
Hvorfor bruge vores frie stemmeoptager?
Hurtig server-sidebehandling
I modsætning til browserbaserede konvertere, der er begrænset af din enhed
Batchkonvertering
Upload multiple files at once and convert them all with the same settings. Whether you need to convert 5 podcast episodes from WAV to MP3, or transcode an entire folder of game audio assets to OGG, our batch processing handles it efficiently. Download all converted files as a single ZIP archive for convenience.
Kontrol af kvalitet og format
Vælg mellem tre kvalitet forudindstillinger (lav, Medium, høj), der styrer prøvehastighed og kanaltælling, og tre output-formater (WebM for mindste filer, MP3 for kompatibilitet, WAV for tabsfri kvalitet). Vælg din foretrukne mikrofon fra en liste over tilgængelige enheder. De anslåede filstørrelse opdateringer i realtid, så du ved præcis, hvor meget opbevaring din optagelse vil bruge.
100% browserbaseret og privat
I modsætning til andre online stemmeoptagere, der uploader din lyd til deres servere, behandler vores optager alt lokalt i din browser ved hjælp af Web Audio API og MediaRecorder API. Din lyd forlader aldrig din enhed, medmindre du udtrykkeligt vælger at sende det til et andet værktøj. Ingen data indsamles, ingen konti kræves, og ingen servere involveret i selve optagelsesprocessen.
