This is a list of 3 free online frequency sweep generator. They can be used to generate frequency sweep tones by setting two different frequencies (start and end) and a time duration for frequency sweep playback. After you set the start and stop frequencies, these online frequency sweep generator will automatically generate the tone and apply the frequency sweep. When you play the tone, it will begin from the start frequency and sweep towards the end frequency in accordance with the time interval set by you. You can also choose between two different sweep modes named, Linear and Exponential (logarithmic) for better hearing of the tone.
If you choose the logarithmic sweep mode, then these online frequency sweep generator will quickly sweep the higher frequencies during the playback. Whereas, selecting the linear mode will change an equal amount of frequency over equal time durations. Each of them also come with some unique features using which you can manually select the waveform, tone volume, sample rate, and even download the frequency sweep tone.
There are many online services available using which you can easily shift pitch or change tempo of audio files. But, when it comes to generating frequency sweep, then there are very few services which can help you do that. So, after spending a lot of time, I have come up with these 3 free online frequency sweep generator.
Sweep Generator:
Sweep Generator (by Online Tone Generator) is probably one of the best online frequency sweep generator using which you can easily generate tones with a frequency sweep. It allows you to set two different frequencies and then specify a time duration to generate a tone. In addition to that, you can choose any predefined waveform among Sine, Square, Sawtooth, and Triangle. You will also see the options to enable Linear or Exponential sweep mode and change the volume (start and end). It lets you play the tone containing frequency sweep using the built-in player. The only drawback of “Sweep Generator” is that it doesn’t have any option to download the frequency swept tone.
How to Generate Frequency Sweep Tone using Sweep Generator:
Step 1: To get started, simply browse the “Sweep Generator” homepage and there you will see the options to set the frequencies (start and end) and time duration (in seconds). You can enter any value you want in the frequencies and time field.
Step 2: After that, you can go ahead and choose any of the predefined waveforms among Sine, Square, Sawtooth, and Triangle. At the bottom of the waveform option, you will also see another option to choose the sweep mode as Linear or Exponential.
Step 3: When you’re done selecting a sweep mode, you can proceed and set the start and end volume of the frequency sweep tone. Once you do that, you can hit the “Play” button to listen to the tone which you have generated. Unfortunately, it doesn’t have any option to download the tone. However, you can use free software to record PC audio to record that tone on your PC.
Sweep Tone Generator:
Sweep Tone Generator is another useful online frequency sweep generator using which you can create frequency sweep tones with ease. To create a frequency sweep tone, you can simply enter the start and stop frequencies and set the time interval in seconds. Apart from that, it also allows you to set dBFS (decibels relative to full scale), sample rate, switch sweep mode (linear or logarithmic) and add audible markers. Unlike “Sweep Generator”, this one doesn’t have any option to play the generated tone but instead allows you to download the tone as a WAV file. After that, you can play that tone using any of the audio players you want.
How to Generate Frequency Sweep Tone with Sweep Tone Generator:
Step 1: Go to the homepage of “Swipe Tone Generator” and there you will see the options to generate frequency sweep tones. The first thing you would need to do is set the “Start Frequency” and “Stop Frequency” by entering any value you want.
Step 2: After setting the frequencies, you can define the dBFS level (in the range of -72 to 0), set the time duration (in seconds), and choose a sample rate (8 kHz, 16 kHz, 48 kHz, etc.).
Step 3: Once you’re done with these options, you can go ahead select the sweep mode. By default, the sweep mode will be linear, but you can toggle logarithmic mode by enabling the “Log Sweep” option. Another useful option offered by this online frequency sweep generator is audible markers. When you enable the audible markers, it will generate short pulses every 10 Hz, 100 Hz, and 1000 Hz to help you figure out resonance.
It doesn’t come with a built-in player using which you can listen to the frequency sweep tone. However, you can click on the “Download” button to export the tone as a WAV file on your PC.
Wav Tones:
Wav Tones can also be used to generate frequency sweep tones online. Using this online frequency sweep generator, you can also manually set the start and stop frequencies and assign the playback time duration for the tone. Similar to Sweep Tone Generator, this one also allows you to define dBFS, sample rate, and add audible markers. Apart from that, you can also change the sweep mode from linear to logarithmic or vice versa. This sweep generator also doesn’t have any option to play tones but allows you to download them as WAV files.
How to Use Wav Tones to Create frequency Sweep Tones:
Step 1: First, visit the “Wav Tones” homepage and there you will see various options like Tone, Burst, Dual, Warble, Sweep1, etc. Here you would need to select the “Sweep1” option to proceed for generating frequency sweep tones.
Step 2: Once you do that, you can enter any (Hz) value in the input fields of “Start Frequency” and “Stop Frequency”. After that, you can set a value for dBFS and then assign the time duration of tone playback.
Step 3: When you’re done setting frequencies, dBFS, and time duration, you can go ahead and select the sweep mode. Initially, the sweep mode will be “Linear” but you can enable the “Log Sweep” option to switch the sweep mode to “Logarithmic”. You can also add audible markers such that short pulses will be added to the tone every 10, 100, and 1000 Hz.
When you’re all set, you can choose a sample rate and click on the “Download” button to save the tone as WAV file. There is no option to play the tone online.
Closing Words:
These are some of the best free online frequency sweep generators which can easily assist you in creating frequency sweep tones. They can come in handy if you want to measure the response of your amplifiers, or detect resonances, etc. Personally, I like all of them as they serve their purpose effectively.
Try them out and do let us know if you’re familiar with some other online frequency sweep generator.
