《比位率指南》
- 64 kbps - 低质量。 仅使用语音/ 语音, 文件非常小。 适合带宽有限的播客 。
- 128 kbps - 标准质量。 允许随意监听。 质量和文件大小的平衡良好。
- 192 kbps - 质量高,比128k有明显改善,对音乐图书馆有好处。
- 256 kbps - 质量很高,对大多数听众和设备来说 近乎透明
- 320 kbps - 最大 MP3 质量。 几乎无法与无损区分 。
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
音频转换如何工作
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.
选择输出设置
从 9 种可用的选项中选择您想要的输出格式 。 用位速率控制( 64 - 320 kbps for lossy 格式) 、 样本率选择( 22. 05 kHz to 48 kHz) 和频道配置( 保持原版、 转换为单体或转换为立体) 进行精细调质量 。 WAV 和 FLAC 等无损格式忽略比特率设置, 因为它们保存完整质量 。
下载您的音频
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.
为什么使用我们的免费录音机?
快速服务器- Side 处理
与受设备限制的基于浏览器的转换器不同
批次转换
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.
质量和格式控制
选择三种质量预设( Low, Miden, High), 控制样本率和频道计数, 三个输出格式( 最小文件的WebM, 兼容性的MP3, 无损质量的WAV) 。 从可用的设备列表中选择首选的麦克风。 实时更新文件估计大小, 以便您知道您的记录将使用多少存储 。
Private & Secure
与其他将您的音频上传到服务器的在线语音记录器不同,我们的记录器使用Web Audio API和MediaRecorder API,在浏览器中处理所有本地内容。您的音频不会离开您的设备,除非您明确选择将其发送到另一个工具。没有收集数据,不需要账户,也没有服务器参与记录过程本身。
