Visualize heart and lung sounds with the Thinklabs Wave app and other software applications. Visualizing heart and lung sounds is a good adjunct to listening. Expand the capability and power of your Thinklabs digital stethoscope by capturing sounds on your mobile devices, laptops, PC or Mac. Once you've captured the sounds, audio software gives you the power to display, edit, amplify, filter, slow down playback rate, show spectrograms and more.

The Thinklabs Wave App provides easy visualization and editing of heart sounds and lung sounds recorded from your Thinklabs Digital Stethoscope. The software can be downloaded free and works with both PC or Mac computers and Android/iOS devices. With the Thinklabs Wave app, you can use your Thinklabs Stethoscope to take auscultation to a whole new level, whether you are in Medical Education or Clinical Practice. Here are just some of the features and benefits:


Easy to Use 


- Record and Playback sounds as if you are using a simple tape recorder.

- Display and visualize sounds very clearly and intuitively.

- Manipulate and edit sounds with ease.

- Save results easily in sound files or group sets of sounds in Project files.


Capture Sounds

- Record from your Thinklabs Stethoscope directly to a Notebook Computer.

- Import recordings from your iPhone, iPad, Android, or digital audio recorder. Sound files can usually be emailed from almost all mobile apps, making transfer to the computer easy.

- Import recordings from email attachments or downloaded from the Internet.


Playback and Export Sounds

- Play back sounds on your Mac/PC and listen with Thinklabs headphones - ideal for high clarity.

- Edit and Export sounds to new files for lectures, emails, podcasts, cloud server collections and telemedicine.


Visualize Sounds

- Display heart sound Waveforms.

- Display lung sound Waveforms.

- Display Spectrograms (frequency spectrum) of heart sounds and lung sounds.

- Display Waveform and Spectrograms together to correlate timing and frequency.

- Display FFT’s of a segment of sound to observe frequency content.


Manipulate Sounds

- Amplify Sounds after they have been captured.

- Filter recorded sounds to refine recordings or look for specific sound characteristics. Both standard pre-set filters and user-defined filters can be used.

- Rate Change – Slow down recordings so that details such as splits are more audible.


Edit, Annotate and produce Electronic Medical Records

Cut, Copy or Paste sound segments.

- Label Sound tracks to identify specific events such as S3, S4, murmurs, etc.

- Import groups of sounds for one patient, or a group of patients into Projects that can be saved, so that you can later open a single Project file to access all related Sounds.

- Save images of Waveforms and Spectrograms along with Labels for medical records or research papers.


Auscultation Research for Advanced Users

- Investigate heart sounds and lung sounds for new diagnostic methods.

- Develop software analysis methods. 


Other Software Applications


Besides the Thinklabs Wave app, consider the following audio processing software packages:


Audacity - This is the full-blown version of the software on which Thinklabs software is built. Audacity has a full complement of filtering and signal processing functions that we removed from the Thinklabs packge for simplicity. Audacity is free since it's a open source project. Learn more about Audacity.


Twisted Wave - For Mac users (and iPhone and iPad), TwistedWave is a very cool software package. There's also a cloud-based recorder that works right in your browser. The beautiful thing about TwistedWave is its ability to share sounds from an iPad or iPhone, just terrific for teaching around the bedside. You can do filtering on the iPad or Mac version. Learn more about TwistedWave.


Adobe Audition - If you really want to do some heavy lifting, Adobe Audition is an excellent audio editing package. You can subscribe monthly to use it but if you're in academia, there are some excellent prices to use Adobe products. If you're preparing professional-grade materials, look at this package. It's not as easy to use as the others. Learn more about Audition.
