Appendix C - Sonor and Sonor Jnr. differences

Although Sonor is a technically more advanced program than Sonor Jnr., it does predate Jnr. by about two years. In that period of time, new technologies (mostly drag and drop) have been created.

This appendix describes the differences between Sonor and Sonor Jnr., so that if you have used Sonor, then you will be able to quickly get to grips with Jnr.

Alternatively, if you are looking for a more advanced editing package, then you can see what Sonor offers you.

Basic sample editing

Sonor Jnr. does not have any of the following:

Amplify sample; Reverse sample; Echo sample; Fade sample; Silence sample; Filter sample; Change sampling frequency; Add sine wave to sample; Duplicate sample section

Inter-sample merging

Sonor offers the ability to perform average merging (Sonor Jnr. has addition merge), as well as amplitude modulation. You can also insert at the start of the destination sample, at the cursor, or at the end of the destination sample. Merging and overwriting can occur at the start of the destination sample, starting at the cursor, finishing at the cursor, or finishing at the end of the destination sample.

Sample saving

Sonor allows you to explicitly save in a number of formats. However, Sonor will save samples in Armadeus format by default, and will not save samples in the format they were loaded.

Sample Loading

Sonor will import some file formats that Jnr. doesn't, whereas Sonor Jnr imports a few formats that Sonor doesn't.

Sample views

Sonor can open a maximum of 16 samples at the same time, with 32 views in total. Sonor Jnr. can open a maximum of 4 samples, with 16 views in total

Sample playing

Sonor can change the frequency of a sample using a piano-style display. The values can also be entered explicitly. There are also fast play (forwards and backwards) buttons available.


Sonor can display the incoming (and outgoing) sounds as a waveform and a frequency-based analysis graph.

Drag and drop

Sonor has no drag and drop facilities. Sonor Jnr. can merge, insert or overwrite samples by dragging the selected area onto different samples and filer windows.


Sonor treats files internally as 8-bit Acorn µLaw samples. Jnr. uses 8-bit linear by default.

Sonor can trigger an external MIDI device, so that the instrument can be recorded.

Sonor can wait until the signal reaches a certain level before it starts recording.

Sonor Jnr. can change the length of a sample easily.

Sonor has a 1-stage undo/redo buffer.

Sonor can zoom to the selected area

Sonor can record using different devices, other than the standard SoundByte recorder.
