| My audio file will not load | The source may be corrupted, protected, encoded with an unsupported codec or too large for the browser to handle. | Check that the file plays normally elsewhere, confirm the format and try a smaller valid local copy. Avoid renaming an extension as a substitute for conversion. |
| Conversion appears stuck at the start | FFmpeg WebAssembly resources may still be loading, or the browser may be low on memory or CPU capacity. | Try a short file, update the browser, close demanding tabs and retry with fewer queued sources. Check network access if engine resources are not cached. |
| The output WAV is much larger than my MP3 | PCM WAV stores decoded samples rather than compressed MP3 frames, and output size scales with rate, precision, channels and duration. | Choose a destination-appropriate PCM format and remove unneeded channels only if safe. Keep MP3 or use FLAC when compact storage is more important. |
| The WAV file has no sound | The wrong stream may have been selected, the source could contain silence, or a processing setting may have muted the signal. | Listen to the source, inspect the waveform and output channel settings, disable optional effects, then convert a brief test section. |
| The recording sounds distorted after converting | The source may already be clipped, a gain or EQ effect may be excessive, or an export stage may have insufficient headroom. | Compare the source and WAV at matched volume, disable normalization or boosts and retry with suitable processing headroom. |
| My WAV sounds no better than the MP3 | The original MP3's lossy encoding already removed or changed some signal information. | Use a higher-quality source when possible. Treat WAV as an editing-friendly representation, not an audio reconstruction tool. |
| A 32-bit float WAV will not play in my application | The destination may not accept floating-point PCM, the requested rate or a particular channel arrangement. | Check the application's specifications and try standard 16-bit or 24-bit PCM at a supported sample rate. |
| WAV output has an unexpected sample rate | The export preset may differ from the input, or the destination application may interpret metadata unexpectedly. | Inspect selected settings and file properties; match the required project rate and reconvert if necessary. |
| Audio plays too fast, too slow or with the wrong pitch | A speed effect may be enabled or sample-rate interpretation may be incorrect. | Disable optional speed changes, verify input and output rates and compare playback in another compatible editor. |
| Stereo material sounds strange in mono | Downmixing may combine phase-opposed sounds and cause cancellation or altered balance. | Preserve stereo where possible or inspect the downmix in a proper audio editor before exporting the mono WAV. |
| An AC3 or DTS input lost surround channels | The selected output layout may downmix to stereo or the stream decoder may not support the desired arrangement. | Inspect the channel options, test one short surround sample and confirm that the recipient accepts the resulting channel layout. |
| Noise removal makes the voice sound metallic | The denoise effect may be suppressing speech components along with steady background noise. | Reduce the filtering strength or turn the effect off. Use a cleaner source recording when available. |
| Volume normalization made the file too loud | The selected method or target may not match the intended listening or distribution standard. | Check peak and loudness targets separately, reduce gain and verify playback with a trusted meter or editor. |
| The end of the recording is cut off | Trim boundaries, silence-removal settings or processing failures may remove trailing content. | Widen the trim range, disable aggressive silence removal and compare the WAV duration against the original. |
| A URL import is rejected | The host may require authentication, block cross-origin access, disallow direct downloads or use an expired address. | Use an authorized direct link or save a permitted local copy and upload it through the normal file chooser. |
| Batch conversion crashes the browser tab | Too many long or high-rate WAV jobs can exhaust available memory or temporary disk space. | Reduce parallel workload, split the queue and close other tabs. Convert demanding files individually on a capable device. |
| The ZIP download is incomplete | One or more jobs may have failed, or packaging and saving may have been interrupted by limited resources. | Check conversion statuses, download results individually when possible and rebuild smaller ZIP batches. |
| Album art or metadata disappeared | Metadata support differs between audio formats, containers and applications; PCM conversion does not guarantee tag transfer. | Keep the original source and export a separate metadata record or retag the output with a compatible audio editor when necessary. |
| My phone cannot finish a long conversion | Mobile browsers may limit background tasks, memory and storage, especially with high-resolution WAV files. | Use shorter clips, standard output settings or a desktop browser with greater available resources. |
| I am uncertain how confidential recordings are handled | The site promotes browser-based conversion but external URL imports and site services can introduce separate data-handling considerations. | Consult the current privacy policy and your organization’s requirements. Avoid processing sensitive material until the workflow is understood. |
