How to use Interval RecognitionPress the Question Mark button ('?') on the Action Bar or Menu -> Contextual Help to show information about the current Technique / screen. There are Breadcurmb links at the top of each page and links within the text to navigate between help pages.
This app has a lot of options and features to enable you to learn in the way you find easiest. A lot of these features are demonstrated in the video at the top of the page. Please do contact me if you have any questions or feature requests.
- Press Menu - > Technique to choose from Intervals / Phrases / Scales etc. Then choose the note source from Selected Intervals / Notes / a Mode or Scale.
- Selected Intervals / Selected Notes can be changed by pressing Menu -> Select Intervals Etc and choosing Intervals or Notes then making your selection.
- A standard press on Repeat and Next will skip repeat or skip the current question. Long pressing can skip an entire phrase / cluster or repeat just part of a phrase.
- The Play type button selects between Ascending / Descending / Harmonic etc.
Listen / Guess:
- Toggle between guessing the answer to questions and hearing any possible answer by pressing the Listen (or Guess) in the Action Bar. For pre Ice Cream Sandwich devices press Menu -> Listen.
- If your device has a button for Search, this can be used too.
- Touch an Answer to hear it. Touch Repeat to play the Question. Unselected Answers are coloured red but they can still be listened to.
- Press Listen Type in Listen Mode to choose what is played eg Interval / Song / Chromatic etc and direction ie Ascending / Descending
- One way to learn intervals is to associate them with well known melodies which start with (or contain) that interval.
- After an incorrect guess, a melody may be played which is associated with the correct interval.
- To change which song is played: Menu -> Select Intervals Etc -> Songs -> Choose an interval -> Choose Ascending and Descending songs -> OK. Long press a song name to hear it.
- I welcome song suggestions.
- Press the Options Button on the Action Bar (on devices without an Action Bar - Menu -> Options).
- Set the BPM (speed) and velocity (volume) of each note. Notes can be made louder by playing them several times simultaneously. Set the pitch range of notes used for the root note of intervals / phrases / scales.
- Select what response is played after an incorrect guess eg nothing, play the correct interval, a song associated with the correct interval or the incorrect interval followed by the correct interval.
- Choose whether a prompt is displayed after a correct interval / complete phrase. Choose whether the 'ding' and 'buzz' sounds are played to indicate correct / incorrect answers.
- Select the number of notes in a phrase along with the allowed rhythmic denominations.
- Various options for size of intervals in phrases and how modes / scales are used.
What does speech recognition understand in Continuous Play?
Speech recognition in Continuous Play is not yet finished and will be improved in both accuracy and in the number of things you can say to it. It can currently only be used for ascending or descending intervals and supports:
- Next - (Added in v3.48) The same as pressing the Next button. Goes to the next interval.
Note names - (Added in v3.4 and improved in 3.48)
Say just the note name not the octave ie 'C, C sharp / D flat, D, D sharp / E flat, F, F sharp / G flat, G, G sharp / A flat, A, A sharp / B flat, B'.
Pause - (added in v3.4)
The same as pressing the Pause button during Continuous Play. You must press the Continue button to carry on.
Repeat - (added in v3.4)
The same as pressing the Repeat button during Continuous Play.
Root note - (added in v3.48)
The root note of the interval will be displayed (and announced if you have that option enabled).
Stop - (added in v3.4)
The same as pressing the Stop button during Continuous Play.
If these errors or any other problems persist, please contact me with a description of the problem, any error messages and the model of your device.
#1000 - Error creating midi file...
If using midi sounds instead of HQ sounds - the application will create a midi file and attempt to save it to Internal Storage - if that fails then this error occurs.
#2000 - Error playing midi file...
The midi file was created but the media player can't play it.
#3000 - No activity found for Speech to Text...
Interval Recognition relies on a separate service for speech recognition. Many android devices use Google's service but there are other options.
#3010 - Cannot start Text To Speech...
Interval Recognition optionally uses Text To Speech. It requires the English Language Locale to be installed. When the app starts it tries to initialise Text To Speech. Check Text To Speech is installed and make sure it isn't being used by another app.
Interval Recognition requires Internet Permission for the following:
- To use BugSense for crash reporting - this assists me greatly in fixing bugs.
- Google Analytics to track how often the app is used and which features are used most.
- Google AdMob to display adverts - not in the Donate version.
- Speech recognition during Continuous Play.
- This application does not require internet permission for normal functionality and will work without it (except speech recognition).
- Network State Permission is required by AdMob and Google Analytics so it can try to wait until wifi is available.
TranslatorsI have had some requests to translate this app into other languages - something I never imagined would happen when I started writing it - so Thank You. I then received offers from users to help with the translation - so Thank You again!
Android apps handle localisation by each language having its own file and each piece of text having a unique name; thus every translation of the same phrase shares the same name. Translations can also use arrays (which are like lists) to group similar items - eg the first position of a list called 'Interval Names' will be the word for 'Unison' in the required language.
Even I was a little surprised at how much text this app uses. So I thought the best solution is to make the translation a collaborative effort whereby individuals can translate whatever parts they wish.
To help translate this app, please update this Google Sheets file.
It contains a separate sheet for each language. Sheets are named by their country code and language - please make sure you update the correct one! The 'en-english' sheet cannot be edited and is referenced by all the other language sheets - thus the first four columns are exactly the same for all languages and the phrases are in exactly the same order for each language.
- Phrases are mostly grouped by their use within the app eg for a particular technique or how they are displayed eg lots of Button texts are grouped together.
- Column A - contains comments / explanations / examples. The text is green.
- Column B - contains the name of a list - above the 1st item in a list. Below the last item of a list - Column B contains '### end of list ###'
- Column C - contains the name of each phrase. This column is blank for lists.
- Column D - contains the English phrase to be translated. Columns A, B and C - do not need to be translated!
- Column E - contains the translated text - well if all goes to plan it will!
- If the text in Column D is red - it indicates that row in Column E is blank.
- Some characters have special functions eg \ and % so must occur twice to be displayed once.
- Some phrases need numbers or other information (variables) to be placed within them. Most commonly %1$d is used. %1 means the first variable supplied (there could be more than one and they can appear multiple times in the desired order). $d means a number. $1%s means text instead of a number. Eg 'Tempo: %1$dbpm' may output 'Tempo: 120bpm'.
Thank you for your help! The app does not read directly from the Google Sheets file - new translations should be included in the next update.

I am an individual developer working on this app (and others) in my spare time. Thanks for using / considering this app - I hope you find it useful.Google AdMob:
The free version of Interval Recognition uses Google AdMob to display personalised adverts.
From the 'Layout and Fonts' screen you can choose either Banner or Interstitial ads. If Banner ads are selected and there is no internet connection, the layout will automatically adjust and not waste space with blank adverts.
The Donate version does not display adverts but contains essentially the same code and references the AdMob library - but ads are not loaded or displayed.Google Analytics:
This app uses Google Firebase Analytics to give me an idea of how many users the app has, what features are popular and how long the app is used for.Android Advertising ID:
This is a unique (but user-resettable) string - similar to a cookie.
AdMob uses the Android Advertising Identifier to display personalised ads.
Google Analytics also uses the Android Advertising ID.
The Android Advertising ID is user resettable from the Google Settings.Google Firebase Crashlytics:
This app uses Google Firebase Crashlytics to report crashes. This will provide me with a stack trace (details of what line of code caused the crash and how the app got to that line) - which I will use to understand the problem, try to replicate it and hopefully fix it.
Along with the stack trace, I also receive some device information - eg device model, language, OS version, app version etc. This helps me understand the reason for the crash.Internet Connection:
The app works fine without an internet connection - except for maybe speech recognition in continuous play which uses the Google speech recognition service.Communication:
I welcome comments and suggestions - it is encouraging to hear from users - thank you. If you choose to contact me, I will try to reply in a timely manner. I will most likely contact you again some time later when I have released an update or to let you know about progress relating to your original question. I will not pass your details on to anyone else.Jump to section
