Guida al bitrate

  • 64 kbps - Bassa qualità. Solo voce/voce, file molto piccoli. Adatto per podcast dove la larghezza di banda è limitata.
  • 128 kbps - Qualità standard. Accettabile per l'ascolto casuale. Buon equilibrio di qualità e dimensioni del file.
  • 192 kbps - Alta qualità. Miglioramento osservabile oltre 128k. Buono per le librerie musicali.
  • 256 kbps - Altissima qualità. Vicino-trasparente per la maggior parte degli ascoltatori e attrezzature.
  • 320 kbps - Massima qualità MP3. Praticamente indistinguibile da senza perdita.

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

Come funziona la conversione audio

Convert between any audio format in three easy steps. Our server-side FFmpeg pipeline handles all the heavy lifting.

Fase 1

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.

Fase 2

Scegliere le impostazioni di output

Selezionare il formato di uscita desiderato dalle nove opzioni disponibili. Qualità fine con controllo bitrate (64-320 kbps per formati lossy), selezione del tasso di campionamento (22.05 kHz a 48 kHz), e configurazione del canale (tenere originale, convertire in mono, o convertire in stereo). Formati senza perdita come WAV e FLAC ignorano l'impostazione bitrate poiché conservano la qualità completa.

Fase 3

Scarica il tuo audio

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.

Perché utilizzare il nostro registratore vocale gratuito?

Elaborazione rapida del server-side

A differenza dei convertitori basati su browser che sono limitati dal dispositivo

Conversione batch

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.

Controllo qualità e formato

Scegliere tra tre preset di qualità (basso, medio, alto) che controllano la frequenza di campionamento e il numero di canali, e tre formati di output (WebM per i file più piccoli, MP3 per la compatibilità, WAV per la qualità senza perdita). Selezionare il microfono preferito da un elenco di dispositivi disponibili. Le dimensioni del file stimato aggiornamenti in tempo reale in modo da sapere esattamente quanta memoria la registrazione utilizzerà.

100% basato su browser e privato

A differenza di altri registratori vocali online che caricano l'audio sui loro server, il nostro registratore elabora tutto localmente nel browser utilizzando l'API Web Audio e MediaRecorder API. L'audio non lascia mai il dispositivo a meno che non scegliate esplicitamente di inviarlo ad un altro strumento. Non vengono raccolti dati, non è richiesto alcun account e nessun server coinvolto nel processo di registrazione stesso.

Domande frequenti

We support conversion between MP3, WAV, OGG, FLAC, M4A, AAC, WMA, AIFF, and WEBM. You can also adjust bitrate, sample rate, and channels during conversion.

The maximum upload file size is 50MB. There are no limits on output file size. This tool is completely free with no account required.

Converting from a lossless format (WAV, FLAC) to a lossy format (MP3, OGG) will reduce quality. Converting between lossless formats preserves quality. Converting from lossy to lossy at a lower bitrate will degrade quality. For best results, use the highest bitrate available.

The web interface processes one file at a time for instant conversion and download. For batch conversion of multiple files, use our API to automate the process programmatically in your preferred language.

Yes, common metadata like title, artist, album, and genre tags are preserved when converting between formats that support them (MP3, FLAC, OGG, M4A). Cover art is also transferred when the output format supports embedded images.

Yes, you can select the output sample rate (22.05kHz, 44.1kHz, 48kHz, 96kHz) during conversion. Upsampling from a lower rate does not improve quality, but downsampling can reduce file size when full quality is not needed.

Yes, you can select mono or stereo output during conversion. Converting stereo to mono reduces file size by roughly half and is useful for speech recordings. Converting mono to stereo creates a dual-channel file but does not add spatial information.

Audio conversion is very fast, typically completing in 2-10 seconds for a standard-length track. Larger files or lossless output formats may take slightly longer. The converted file downloads automatically when ready.

WAV and FLAC are our lossless format options. WAV is uncompressed and universally compatible. FLAC uses lossless compression to reduce file size by 40-60% without any quality loss — ideal for archiving.

Yes, the audio converter is completely free with no account required and no usage limits. It uses zero credits for all users. Convert as many files as you need at no cost.

Yes, we support WEBM and M4A formats commonly used by streaming platforms and web recorders. You can convert these to standard formats like MP3 or WAV for broader compatibility with audio players and editors.

Volume normalization is available as an option during conversion. This adjusts the audio level to a consistent standard, which is useful when processing files from different sources that have varying loudness levels.
