Inverter audio online

In Spanish, people search inverter audio, invertir audio, and audio invertido when they want a file to play backwards. In English studio vocabulary, invert usually means polarity: turn the waveform upside down without changing time. This page follows the Spanish search intent—time reverse—and states the engineering distinction so mix engineers are not misled.

The article is in English because the product UI is English. The editor is the same one as the rest of the site: in-browser reverse, local processing, WAV download.

Dutch searchers with the same job land on audio omkeren. The DSP does not change with the language of the query.

Time reverse versus polarity (invertir polaridad)

Time reverse (reproducir al revés): sample index i plays at index N-1-i. Speech starts on the last syllable. A cymbal decay becomes a rise.

Polarity invert (invertir polaridad / invertir fase): each sample multiplied by −1. Playback still starts at the beginning. Two opposite-polarity copies of the same mono file sum toward silence.

This website implements the first operation only. There is no Ø button. If you arrived from a search that meant to fix a thin snare in a mix, open a DAW. The long-form English explainer is phase invert audio online.

“Flip” in casual Spanish/English bilingual forums also wanders between reverse, polarity, and L/R swap. Flip audio pins flip to time reverse on this site.

How to reverse (the Spanish-intent job)

1. Sube / upload MP3, WAV, FLAC, OGG, M4A, or AAC, or record up to 60 seconds with the microphone.
2. El proceso es local: the buffer does not go to a render farm.
3. Press Play. You should hear the end of the file first.
4. Speed controls are preview only (solo preescucha), not printed into the download.
5. Download WAV.

If the file was already audio invertido in time, reverse again to restore order (unreverse audio). Fades at the edges mean it is not a bit-identical restoration.

There is no Spanish-language karaoke catalog, no YouTube downloader, and no polarity checkbox hiding under an “avanzado” menu.

Why searches mix the words

Tutorials translate “reverse audio” as “invertir audio” because everyday Spanish invertir includes “turn around.” DAW manuals then use invertir fase for polarity. Google lumps them. This URL exists so the wrong mental model is corrected in the first screen of copy, while the player still does the backwards-playback job the majority of searchers wanted.

If you needed an EQ-style “filter” named reverse, that is also not polarity and not a band-pass; reverse audio filter.

Quality and formats

Lossy MP3 stays lossy after reverse; the WAV wrapper is PCM of the decoded buffer (MP3 reverser). Do not expect a hi-res master from a voice note.

Chat apps: export the file, then upload. This page does not log into WhatsApp or Telegram.

Video: extract audio yourself; this tool will not reverse a picture. Replace the track in an editor afterward.

Legal

Invertir a commercial song does not create a new license. Use material you have rights to process.

This site is not a Spanish support desk; the FAQ above is bilingual only where a term clash causes errors. The buttons in the editor are the English labels on the rest of the site.

Other Spanish phrases that mean this job

• reproducir al revés — the accurate description of time reverse.
• audio invertido / canción invertida — often a YouTube title; you still need a file, not a link.
• volteer el audio / voltear — informal “flip”; time reverse here, not stereo.
• poner el audio al revés — same intent.
• invertir la fase / invertir polaridad — not this page.

Mexico, Spain, Argentina, and other locales share the invertir search even when everyday speech prefers al revés. The editor does not switch copy by Accept-Language. Record still says Record.

If you needed Portuguese inverter áudio, the same time-reverse warning applies; this article stays English.

Workflow examples for Spanish-intent jobs

Nota de voz. Export from WhatsApp or Telegram, upload the OGG or M4A, download WAV, send it back. No login on this site.

Clase. Record a sentence under 60 seconds, reverse, send students the WAV. They reverse again to grade. Not a generador de voces.

Mezcla. If a YouTube tutorial said “invierte el audio del canal” next to a Ø icon, they meant polarity. Close this tab and open the DAW. If they showed a region turning around on the timeline, they meant reverse; this tab can do that to an exported bounce.

TikTok. Reverse here, import there. Invertir the song does not clear SGAE/rights issues.

Keep original.wav and invertido.wav as names if that matches how you think. The files are still PCM. Two inversiones of time restore order with edge fades—not a bit-perfect archivo original.

For polarity vs time, the English glossary is on phase invert audio online. For Dutch omkeren, see audio omkeren. This page stays the Spanish-intent landing: same engine, explicit that invertir here means backwards playback.
