1. macOS WiFi Analyser

macOS itself comes with a Wireless Diagnostics tool which you can use to scan all available wireless networks and get a summary of all the channels that your device can connect to. From the summary, it is able to suggest the best 2.4 GHz or 5GHz channel or network suitable for you. It can also be used to monitor the network performance, get log information and even as a sniffer to capture WiFi traffic.

To access it, while holding the Option key click on the WiFi icon in the menu bar and you should see an option as “Open Wireless Diagnostics” which should take you to your built-in WiFi analyzer. Or simply you can also open Spotlight Search and type in “Wireless Diagnostics”.

Pros:

• Network Scanner
• Monitor performance of connected WiFi
• Log Info
• Channel Suggestions

Cons:

• Non-intuitive UI
• No graphical representations

Verdict:

You can get away with the Wireless Diagnostics tool if you need to troubleshoot some minor issues in your personal network. Although it is not very powerful, given it comes built-in and free, you can’t really complain.

2. WiFi Signal

WiFi Signal is one of the more simpler apps on this list which provides all the information you need about your wireless network in a compact and elegant card fashion. The app lives on your menu bar, the icon of which can be fully customized and clicking on it gives you everything from the Signal to Noise Ratio (SNR) to the max data rate and MCS index of your connection. There is a real-time graphical representation of the signal rate and noise rate and the app can also recommend the best channel.

Pros:

• Customizable menubar icon with live signal rate
• Simple at a glance information
• Notifications support
• Channel recommendations

Cons:

• Info of only connected network
• No WiFi scanner

Verdict:

If you are someone who needs to check the strength or quality of your current network from time to time, this app provides you all the info in an elegant card fashion along with a customizable menu bar icon.

3. WiFi Explorer

WiFi Explorer is one of the highest rated WiFi analyzer apps on the Mac App Store and rightfully so. The app does a great job at scanning, monitoring, and troubleshooting wireless networks.

The app provides various real-time graphs for network details, signal strength, and spectrum which makes it much more intuitive for even a normal person to effectively use the app. Apart from the details of your connected network, the graphs also display all the networks your device can connect to, along with all their details which comes in really handy for choosing the strongest access point for your computer. A bonus feature of this app is that you can save all the results for a later review and even export all the network details as a CSV file.

Pros:

• Graphical visualizations of the WiFi environment
• Detailed descriptions of access points
• Exportable to CSV format

Cons:

• Pricey for the number of features it offers
• No menubar icon

Verdict:

Wi-Fi Explorer is great for quickly identifying channel conflicts, signal overlapping or configuration problems that may be affecting the connectivity and performance of your home, office or enterprise wireless network.

Download WiFi Explorer ($19.99)

4. Wifi Scanner

The next app on our list is WiFi Scanner which adds a number of nifty features to the standard WiFi analysis tool.

Like the previous apps, it comes with various real-time and color co-ordinated graphs of the various available networks and provides details about them. But it doesn’t stop there as WiFi Scanner also brings a built-in WiFi speed testing feature that showcases the ping, download and upload speeds of your network to troubleshoot WiFi networks. There is also an extremely useful IP Scanner feature which will give you a list of all the devices that are connected to your network which is great for finding those WiFi “piggybackers”.

Pros:

• Real time graphs and detailed network parameters
• Speed Testing tool
• IP Scanner
• Exportable to CSV format

Cons:

• No menubar icon or way to quickly glance at any info without opening up the app

Verdict:

Personally to me, WiFi Scanner seems the most bang for your buck and with all its features it functions like an all-in-one from scanning available networks and their performances to seeing which devices are connected to my network.

5. NetSpot

NetSpot offers the convenient visual heat maps so you can easily catch any dead spots and how you can optimize access points locations; it is a WiFi analyzer tool like no other!

The app allows you to directly upload a map of your area or draw one using NetSpot’s map drawing tool. Once you have completed that, you can select between several visualizations like signal level, noise level, and access points which show you everything throughout the whole map in the form of heat maps. You can then identify the areas with low signal strength or problems and troubleshoot them.

Pros:

• Full Network analysis and surveys
• Support for area plan or map
• Heat map visualizations
• Suitable for commercial use

Cons:

• Very pricey for personal use

Verdict:

NetSpot feels like a well polished complete WiFi analyzer app. It does feel a little redundant for personal use but with its commercial licensing, it should work great for commercial use or large office areas to detect dead zones and improve the overall connectivity of the area.

6. Honorable Mentions

WireShark is an open source and very powerful network analyzer used mainly by network admins and developers. Although it comes with a steep learning curve, it is one of the best packet analyzer apps available. WireShark is also capable of working in monitor mode, thereby letting you see what other devices are browsing/watching on your network. While normally you’d need an external WiFi adapter to these kinds of things, most Macs have a network card that supports monitor mode which overall works out pretty well.

JamWiFi is another free little tool which can not only analyze devices connected to your wireless network, but you can also disconnect them from using your WiFi. But it also comes with a downside which is it will also disconnect you and you have to reconnect again.

WiFi Signal Strength Explorer is a handy little utility which unlike the normal WiFi icon, shows you the strength of connection via dots/percent in the menu bar and by clicking it, you can access some basic details about your current network.

Wrapping Up: WiFi Analyser for Mac

So these were the best WiFi analyzer applications available for macOS and here’s a little recap. For casual use or not too deep analysis, the Wireless Diagnostics seem to work just fine. If you need something quick that shows you details about your connected network just from your menubar, check out WiFi Signal. As a WiFi analyzing tool, WiFi Explorer has got everything you might need. However, if you are a sucker for extra features, WiFi Scanner provides the most for your money. For large organizations or commercial purposes, nothing comes close to NetSpot. Did we miss anything? Which one do you use? Let us know in the comments below.

Lossless audio is a wonderful thing! By using lossless audio you know that the source material is not the weak link. But have you ever thought “are my FLAC files true lossless audio, or were they upconverted”? Some stores have been caught selling audio of lesser quality packaged as FLAC.

Spek Acoustic Spectrum Analyser

The good news is that it’s easy to find out!

We are going to use a spectrum analyzer to inspect the true bitrate of the files. A good and popular choice for this is Spek (http://spek.cc), which is available for Windows, Linux and macOS.

When we open a file in Spek, we will see a spectrum display of the entire file. Depending on the frequency at which it cuts off, we can determine the bitrate.

Generally these are the numbers to go by:

Spek Spectrum Analyzer For Mac Catalina Island

• 11 kHz = 64 kbps
• 16 kHz = 128 kbps
• 19 kHz = 192 kbps
• 20 kHz = 320 kbps

If there is no cutoff, the file is most likely lossless.

Let’s look at some examples. Here I’m looking at a legally acquired track. I have imported it for personal use from a CD I bought, but I also bought the official download in 96 kHz, 24-bit so I am also going to compare to that.

First we can see a spectrum we really don’t want to see. This is what the 44 kHz, 16-bit file looks like after being converted to a 128 kbps MP3 and then converted to FLAC. There is a sharp cutoff at 16 kHz. This audio is not lossless.

Spek Spectrum Analyzer

Next let’s take a look at a 320 kbps MP3 converted back to FLAC. This time it cuts off at 20 kHz, consistent with the table above for a 320 kbps file.

This below is what a 44 kHz, 16-bit file should look like. It goes all the way up to 22 kHz with no cutoff below.

Now, let’s look at something with a bit more headroom. This is the 96 kHz, 24-bit file. It’s fairly obvious that this file goes well beyond the hearable range, which tops out at about 20 kHz. There is great debate on whether or not anything above that actually contributes anything to the experience or not. I know I can’t tell a 96/24 and 44/16 file apart.

If you want to check a lot of files this method can be a little bit tedious, but fortunately there is a tool for that too. I don’t know if it can be fully trusted, I like to see the spectrum myself, but it saves a lot of time. Lossless Audio Checker (https://losslessaudiochecker.com), available for Windows (GUI), Linux and macOS (both command line only). Here’s what it looks like when testing it on my four files used earlier with Spek.

Now all you have to do is try these tools with your files.
