A vocal harmonizer pedal is a type of pitch shifting device that combines an original pitch with its shifted pitch to create two or more notes in harmony. It is a method of pitch shifting that alters the original pitch to produce different pitches at various wavelengths. Often, the device is called a pitch shifter; a device or sound effects unit that raises or lowers the pitch, by a preset interval, gotten from an audio signal.

Vocal harmonizing involves pitch shifting, and there are diverse methods used. One of the simplest methods used is to increase pitch and reduce duration, or increase duration and reduce pitch. The approach here is to keep replaying the waveform of the sound at different speeds than the speed it was recorded. An old way to do this is to use a reel-to-reel tape recorder by changing the drive shaft diameter of the capstan or using a different motor entirely.

Now let’s get back to the characteristics like the speeds of the motor can be controlled using an electronic servo system circuit. A straightforward is by using ‘vari-speed’ capstan motors that allow speeds to change and be achieved more simply. If you use a vinyl record turntable, you can place your finger on it to slow it down with friction, or you can spin it to give it more speed.

Once you’ve finished designing and developing your game, you will want to get the word out there about its potential for rocking the gaming world. More than simply marketing your brand, it is important to consider strategies that will get your game noticed by potential investors.

Maximizing your visibility and setting yourself apart from the competition means doing more than just having an exemplary product and an exciting backstory. Gleaning investors and drawing them in to support your startup will mean investing time, effort, and energy in a self-promotion strategy. Here are a few ideas.

Ask questions on target investors’ social media pages and personal blogs. Cold tweeting, commenting, or emailing every managing partner in an investment firm is not advisable. It is likely that you will come across as desperate or annoying, and you will find it probably not get you far. Instead, start by following them on their social media pages or their personal investor blogs, and look for ways to engage in natural conversation. The objective is not to pitch to them, but find an area where you have a genuine interest and maybe even expertise, and begin a dialogue that will evolve over time. Getting an investor’s attention may be easier than you think if discourse makes sense for the both of you. 

Develop your own social media pages and personal blog. Initiating and maintaining a sophisticated social media presence is key to getting noticed by potential investors.  Using social media platforms such as Facebook, Twitter, and Instagram as tools to broadcast your ideas, making it easier for developers to find you.  Investors are known for being cognizant of innovative ideas and for searching and scanning social media platforms where gamers engage, so don’t hesitate to use your personal and business accounts to reach other gamers as well. Using a blog as a content curation tool will give you another place to naturally develop connections.
