View audio and compare it at the same position
When you open an audio file, you see a player, the waveform, the spectrogram, and audio information. Both standalone files and audio inside tar files are supported.
Check the waveform and spectrogram
The waveform shows the amplitude of the sound over time, and the spectrogram shows the strength at each frequency. Use them to find where sound starts, silent sections, and differences before and after processing.
Analysis results are cached. The first time, you wait for the analysis to finish, but direct playback and analysis take separate paths. You may be able to play the audio before the waveform is ready.
Add the original and processed audio to the synchronized player
- From the file's Actions menu (⋯), select Add to player.
- Do the same for each audio file you want to compare.
- In the Synchronized player at the bottom of the screen, choose a playback position and play all tracks together.
| Control | What it does |
|---|---|
| Play all / Pause | Control several audio tracks at once |
| Seek all tracks | Move every track to the same playback position |
| Mute | Silence that track |
| Solo | Listen to the selected track |
| L / R | Choose the left or right channel of stereo audio |
| Delete | Remove the track from the player |
Removing a track from the player does not delete the file on S3.
If analysis does not appear, check the connection settings
If Audio information and waveforms is turned off for the connection, mado does not run the analysis. Spectrograms can also be restricted per connection.
The input limits for analysis are 2 GiB for standalone audio and 100 MiB for audio inside an uncompressed tar. These analysis limits do not apply to direct playback.
