UpTempo User Guide

This user guide explains how to use the UpTempo Android app developed by Stonekick.

UpTempo allows you to alter the pitch and/or speed of any music file on your Android device.

The pro version of UpTempo also allows you to add additional effects such as Equaliser or Reverb to the track as a whole or to a particular section of the track.

Getting Started

The app will open on the Playlist screen. An example track is included when you first open the app. You can use this straight away.

To add your own music press the + icon in the bottom right hand side of the screen. You can open any music stored on your Android device. However the app is unable to open files from music streaming services.

In the pro version of the app you can also create your own recording here to edit in the app.

Adding a new Playlist

Tap on the down arrow in the top action bar to go to the Playlist screen. Here you will see your saved playlists, or tap’+’ to create a new one.

Using the waveform

When you open a track a waveform will load. Once you press play this will highlight to show where you are in the track.

Click on the waveform to skip to a particular point in the track.

Pinch and zoom to get more detail. Press the zoom icon to view the whole waveform.

Play controls

At the bottom of the screen you will see the player controls.

Use the arrows to the left/right of the Play button to skip between markers on the current track or skip between tracks in your Playlist.

The loop button has a toggle which lets you loop either the current song, or your whole Playlist.

Setting markers and loop points

You can add markers to any point in the track. Press the orange AB icon to bring up the marker controls. Navigate to any point on the waveform and then press + to add a marker. You can also edit the markers from here or choose markers to loop between.

Drag the markers to move them to a new position.

Changing pitch and tempo

You will find the pitch and tempo controls below your waveform. Here you can use the sliders or numerical input to change the tempo and/or pitch.

Press the reset icons to return the track to its original state.

Preserve Formant

Below the Pitch and tempo sliders you will find a ‘Preserve formant’ option.

Formant preserving compensates pitch changes by shifting the timbre back to its natural position.

It makes voices sound more natural at the higher pitches and less ‘squirrely’.

Saving settings/export updated track

Tap on the download icon to export your updated track. You can export in mp3 or m4a format.

You can also save the settings you have put into the app for access later by tapping on the settings icon on the right hand side of the top action bar.

Mixing and merging multiple tracks

When you go to open a track on the Playlist screen, you will see an option to open a new ‘Multitrack’.

This option creates an empty multitrack. Rather than seeing a single waveform at the top of the screen, you will see a button to ‘add tracks’.

Once you’ve added tracks long press on the waveforms to move them in to position. You will also see a mixer at the bottom where you can mute or adjust the volume of individual tracks.

Once you’ve created your multitrack you can change pitch/tempo and apply advanced effects in the same way as with a single track.

Advanced Features

In the pro version of UpTempo you can also add the following effects to a particular section of the track or to the track as a whole:

• Bit Crusher

• Delay

• High or low pass filter

• Noise Gate

• Panning

• Ring Modulator

• Mute Bass/Center/Sides

• Equaliser

• Pitch/Tempo

• Compressor

• Reverb

Exporting your Up Tempo settings

Up Tempo will regularly export your Up Tempo settings to a folder on your device. This includes markers, effect settings, loop points, multitrack files etc.

IT WILL NOT BACK UP ANY AUDIO FILES INCLUDING RECORDINGS THAT YOU CREATE.

UpTempo has lost the songs on my SD card. What can I do?

UpTempo uses the Android media library to search for and open songs on your device. Unfortunately the Android media library can sometimes lose the link to tracks on your SD card and then UpTempo can no longer open them.

If this happens you will need to add the tracks again to your Playlist:

• Tap on the + button and search for the track again in the library

• If you can’t find the track in the library, try using the file browser by tapping on the storage icon in the top right hand corner of the library screen action bar.

The safest option to ensure this doesn’t happen again is to copy any tracks which are on your SD card on to your phone.

We are working on a better solution to this issue and hope to release this update soon!

Can I request a new feature?

Definitely. We keep a log of all requests and try to implement them where we can. If you have a request please get in contact with us at [email protected].

I have purchased the pro version of the app. Will this work on my other devices or will I have to purchase it again?

When you purchase an app it is linked to your (Google Play or Apple app store) account. As long as your other devices are logged into the same account, your paid licence will automatically transfer across. Note, however, that your licence won’t transfer between Android and iOS as they are separate apps on the 2 different stores (Google Play and Apple app store).
