This is a very exciting release because it opens up significant new opportunities for TeleTools and your applications.  The essence of the new features center around TeleTools 3.7 vastly enhanced play / record capabilities.

  • Play and Record to memory buffers as well as to disk
  • Fast forward, rewind or pause recording or playback
  • Seek any position in a wav file by time, index, even percentage
  • Trim before or after position and allow splitting or joining wave files
  • Save embedded information and text inside wav files

These new features enable benefits such as dramatically improved single and multi-line performance for wave intensive applications, better voice mail or prompt editing capabilities, and a much more organized approach to managing wave files.  Click here for a more detailed feature list and look below for a description of the new features.

Memory Buffers
Large and even small multi-line systems can get bogged down accessing wave data from the disk. Some telephony tools solve this problem by using indexed audio files, often referred to as VOX. The TeleTools approach of using memory buffers is far more flexible. TeleTools v3.7 allows multiple line devices to share audio data, thereby reducing the number of open files and virtually eliminating disk access delays, all while using standard wave file formats supported by many other telephony and non-telephony applications.

Why is this good? Imagine an Interactive Voice Response system (IVR) supporting 48+ lines simultaneously and, on every inbound call, a greeting wave file is played. Prior to TeleTools v3.7 every new call required the application to locate the disk file, open it and read the data from the disk. Now with TeleTools v3.7, you can use shared memory buffers and the file is read once then stored in memory. Each of the 48+ lines accesses the same data, greatly limiting the potential for disk access errors and delays.

With TeleTools v3.7 wave data storage is flexible with memory buffers. No longer is your application limited to only storing wave files to disk. Now wave data may be stored in a database, as resource items within executables or, as standard wave files for use with other applications that support wave files.

Fast-forward, Rewind and Pause
Voice mail systems and voice-prompt management require the ability to fast forward and rewind as well as pause while recording or playing wave files. With TeleTools v3.7, developing call recording, IVR's, and transcription systems are even easier

Seek and Search through WAV Files
TeleTools v3.7 now allows for flexible positioning of audio play- you can use seconds, bytes, index and, even percentages!  Applications such as medical transcription, dictation, and voice messaging just to name a few just got a whole lot easier to create in v3.7.

Trim Before or Trim After
With the new trim before and trim after properties, TeleTools v3.7 lets you cut, crop, split or join wav files together.  You can more easily write apps that merge audio files and allow users to edit recordings and messages.

Embedded Information
Many telephony applications utilize a large number of audio files. Imagine an audio prompt management module that stores the text within the wave file or, a dictation system where the translated text is added directly to the wave file. Coding, audit trails and disaster recovery are now made easy with TeleTools v3.7.  Few wave audio tools take advantage of the List capabilities that Microsoft designed into the wave audio file API. With TeleTools v3.7 you can add textual information to any, and all, wave files. Wave file management is made easy with fields like Author, Category, Comments, Copyright, CreationDate, Keywords, Subject and Name.
