Voice Recording Samples
Hybrid SDK (Kapsel) applications for Android, iOS and Windows platforms.
Capture Audio
Captures and encrypts audio information.
// You can specify the maxLength (in millisec) for the recording var args = { maxLength: 120000 }; sap.VoiceRecording.audioCapture( function(_recording) { recording = _recording; }, function(error) { console.log("An error occurred at audio capture\n\n" + JSON.stringify(error)); }, args );
Playback Audio
To play an audio recording the application triggers an API function that displays an UI dialog. This UI allows you to play back or seeking position of recording..
// triggering playback screen recording.play( function() { console.log("Play finished Successfully\n\n"); }, function(error) { alert("An error occurred at play\n\n" + JSON.stringify(error)); } );
Recording ID and Metadata
You can know the recording object ID and the metadata information for the recoridng.
// recording id and metadata var recording_id = recording.id // the id can be used to retrieve the recording after restart (the application has to store it) sap.VoiceRecording.get(function(recording) { var restored_recording = recording; }, function(error_code, extra) { // error callback (e.g. recoridng does not exist for the given id) }, recording_id); // Recroding metadata var duration = recording.getDuration(); // retrieve the duration (in millisec) var creationDate = recording.getCreationDate(); // retrieve the date of the recording creation var fileName = recording.getFileName(); // returning the filename of the recording used when the file representation is generated with getAsFile() method // file name can be changed by the application recording.setFileName("new_file_name", function() { // success callback }, funciton(){ // error callback }); <span style="line-height: 1.42857;background-color: transparent;">)</span>
Retrieve Audio
The recordings that you capture using the sap.VoiceRecording.audioCapture method is stored with an identity (ID).
Retrieve Recording by ID
You can retrieve a specific audio recording using the
sap.VoiceRecording.get
method.
sap.VoiceRecording.get( function(recording) { // success callback with the retrieved Recording as parameter , function(error_code, extra) { // error callback (for example, recording does not exist for the given id) }, Id );
Retrieve all Recordings
You can retrieve all audio recordings using
sap.VoiceRecording.getAll
method.
sap.VoiceRecording.getAll( function(retVal) { // success callback with an array of Recordings as parameter }, function(error_code, extra) { // error callback } );
Destroy Audio
You can delete an audio recording using recording.destroy
method.
recording.destroy( function() { // success callback }, function(error_code, extra) { // error callback } );sap.VoiceRecording.destroyAll
You can also delete all audio recordings using the
sap.VoiceRecording.destroyAll
method
sap.VoiceRecording.destroyAll( function() { // success callback }, function(error_code, extra) { // error callback } );
Delete Decrypted File (Windows Platform)
You can use sap.VoiceRecording.deleteFileFromPath method (additional
utility) to delete a decrypted file on Windows platform after the
recording.getAsFile operation. However, for Android and iOS
platforms the application deletes all decrypted files once it is not in
use.
sap.VoiceRecording.getAsFile( function(decryptedFilePath) { // success callback with the decrypted file path // upload or send the file, if this operation runs asynchronously, put the delete function into the callback // call delete sap.VoiceRecording.deleteFileFromPath(decryptedFilePath, function() { // success callback, delete was successful }, function(error_code, extra) { // error callback }); }, function(error_code, extra) { // error callback } );
