Will boosting volume cause distortion?

It can. Peaks that already sat near 0 dBFS will clip when multiplied. 1.5x is the safest. 3x is the most likely to crackle. Listen to the loudest shout in the file. If it squares off, use less gain or keep the original. There is no limiter on this page.

Is this the same as normalising?

No. Normalising aims at a peak or LUFS target. This multiplies by a fixed factor. A quiet file and a loud file both get 2x, so the loud one may clip while the quiet one still sounds timid. For podcast delivery, use a DAW with a loudness meter.

Will this volume booster work on iPhone or Android?

Yes, in Safari or Chrome, for ordinary file sizes. Long WAVs can exhaust phone memory. Boost those on a computer.

Does boosting an MP3 lose more quality?

You get another 192kbps encode plus the gain. The extra loss is usually smaller than the clipping risk. Keep the original MP3. If you still have WAV, boost from that instead of from a 128kbps note you already crushed once.

How loud is 2x gain in decibels?

About +6 dB. That is roughly twice the perceived level on peaks, not a guaranteed doubling of how loud it sounds in a noisy car. Start at 1.5x if you are unsure. Listen on the speakers you actually use before you delete the original.

Is it legal to boost a track I do not own?

Boosting a recording you made is the intended case. Raising a commercial mix to post as your own can still be a copyright issue. Videozify does not store files and cannot check a licence or a store term on disk.

A volume booster raises the level of a quiet recording and writes a new MP3. Videozify applies gain . Pick 1.5x, 2x, or 3x, drop a voice note or a lecture, and download a louder file for a noisy car. Peaks can clip at the highest gain.

How to boost audio volume online

Drop an audio file onto the box above, or click Browse to choose it from disk.
Choose a gain. 1.5x is mild, 2x is about +6 dB, 3x is aggressive.
Press Boost volume and wait until the progress bar reaches one hundred percent.
Download the MP3 and listen for clipping before you delete the original.

Why use a volume booster instead of turning the speaker up?

A volume booster writes a louder file so weak players and noisy rooms have more signal. Phone voice notes land quiet. Zoom exports sit at low levels. A car USB that maxes out still whispers. Raising the system volume on your phone does not change the file you send to someone else.

This filter is ffmpeg volume=. 1.5x is about +3.5 dB, 2x is +6 dB, 3x is about +9.5 dB. There is no limiter. Peaks that were already hot will square off. That distortion is clipping, not a warm saturator. If the take is already loud, you do not need this page.

Output is 192kbps MP3. A second lossy pass applies if the source was MP3. Keep the original. Normalising to a LUFS target is a different job with a loudness meter. This page is a simple gain, on purpose.

Boost after trim and join so you are not managing eight loudness variants. Boost after speed change if the new tempo file still sits low.

Trim first with the audio trimmer. If the source is still a Voice Memo, convert M4A to MP3. This booster already writes MP3.

A volume booster is a gain tool that multiplies a recording's amplitude and writes a louder MP3.

Which gain should you pick?

Start at 1.5x. Listen. If it is still thin, try 2x. 3x is for captures that were almost a whisper. If 3x still is not enough, the mic was too far away and boosting will only raise hiss.

There is no LUFS readout in this tab. Your ears and a car stereo are the test. If you hear crackle, drop a step or keep the original.

Stereo files stay stereo. A quiet left channel and a loud right channel both get the same multiplier. Channel-independent repair is an editor.

Will boosting fix a bad recording?

No. Gain cannot invent a closer mic. Hiss, HVAC, and room echo get louder too. If the take is unusable, re-record. This page is for files that are structurally fine and 6 dB too polite.

Do not boost a mastered song to win a playlist. That is how clipping wars start and how the file sounds worse on good headphones.

Protected files will not decode. Unprotected notes and rips will. This is not a DRM bypass.

Car stereos with a broken volume knob are a real reason this page exists. The file on the USB is what the head unit plays, not your phone's media volume. Boosting 6 dB in the file is how a quiet interview becomes audible at a legal road volume without pinning the dash at maximum.
