Enhancing Music Tracks – Creative Journey

Music has always had the power to transport us to different worlds and evoke a range of emotions. Part of the reason, why I keep various playlists for each memory, location, travel trip, etc. Creating a flawless music track can be challenging, especially when dealing with instrument fluctuations and background disturbances. It was exciting to see the transformation that creative editing can bring when I recently got the chance to help a friend edit his music track. I am, by no means a music producer; but, it was fun while I was standing behind him, listening to the track on a pair of Yamaha HS8 Studio Monitors. The music editing software Ableton seems like a boon to the musicians.

The following are some of the processes and techniques I used (or rather I suggested to use, while he did the work) to enhance the track, resulting in a more polished and captivating auditory experience.

Reducing Vocal Track and Adding Bass:

The recording we had done took place in the balcony of our apartment, this introduced unwanted traffic noises into the track. Pretty sure one guy on the bike was doing rounds on the road just to mess with us. Anyway, to address this issue, I suggested reducing the vocal track at the particular place where the honking (noises) was prominent. By doing so, we minimized the distraction caused by the external sounds and allowed the focus to shift back to the main vocals and instruments.

In addition to reducing the vocal track, I recommended adding a touch of bass to the mix. The bass serves as a foundation for the music, providing depth and enhancing the overall auditory experience. By subtly adding a strum of the bass guitar and boosting the bass frequency, we were able to create a richer sound. It added a new layer of warmth and energy, elevating the track to a more professional level. Fist bump!

Extrapolating and Replicating the Guitar Beat:

A particularly noteworthy part of the song was a section where the vocalist, who also played the guitar, drummed on the guitar to create a beat. The effect of this rhythm, nevertheless, wasn’t as strong as expected. I suggested to extrapolate and duplicate the beat to a new section of the track, this helped to make it more audible and noticeable throughout the track. This made it possible for the beat to stand out from the background noise adding a memorable and catchy component.

Final Notes

As I said, I am by no means a music producer; And, in the world of music editing, having access to powerful software can greatly enhance the creative process for a polished product. Ableton’s comprehensive set of tools and effects enabled us to tackle the specific challenges we encountered during the editing process. Whether it was reducing the vocal track, adding bass, or extrapolating and replicating the guitar beat, Ableton Live provided us with the necessary tools to achieve our desired results.

The software had an extensive library of sound samples and effects, and this helped us to experiment with different sounds, textures, and arrangements to tailor the track to our creative vision.

Special thanks to ChatGPT for helping me rewrite parts of this, refining the language, and adding an unnecessary number of adjectives. Been planning to use it to write a post, and today seemed like the right day.

Sharp skills for IoT

Internet of Things (IoT), even though new, has captured the attention of professionals in a wide variety of fields of interest. The concept of IoT revolves around the inter-connectivity of Devices that are embedded with sensors, software, appropriate network connectivity and latest electronics within it; to create and collate an array of information exchange and making this entire grid of Devices responsive.

Interestingly enough, IoT encompasses the independent technologies and brings everything under one roof. So, there is no such thing as an ‘IoT Engineer’ (yet). During my research in IoT over the past few months, these are some of the things which I have come across, that are considered to be a ‘valuable set of skills’.

Embedded Systems Design

This is where we start digging deep, essentially we are starting to build computers from the scratch again. In other words, we are re-inventing the wheel. Having knowledge and ideas on how to build an Embedded System that can measure, perceive and communicate with other devices no matter how independent they can be – would be a valuable skill. Imagine a bed that can sense your sleep pattern, notify the alarm, open the curtains to let the sunlight in when you wake up, while it starts the coffee maker and plays songs from your playlist while heating up the water for the morning shower. Based on the interface & dependency factors, the system should be able to communicate. Circuit design is one of the most important things that acts as a baseline for IoT. Since, PCB (Printed Circuit Board) designers are adopting 3D printing, the convergence is a boon to many IoT manufacturers. So, knowledge of any of the above goes a long way in the field of IoT.


We talked about how IoT is about responsive devices in a grid; however, they are also predominantly resource-constrained. IoT networks differ from traditional wired computer networks where the TCP/IP protocol suite is being used; even though IoT devices have temporarily adopted the open standards of TCP/IP, they will be moving towards wireless communication and short-range wireless personal network (WPAN) technologies such as Bluetooth, which consume less power and less data. Lately, Mesh networking – which relies on an inexpensive decentralised architecture, is being considered as a commendable option currently. In addition to that, a possibility of a new protocol/standard could be designed – which means that knowledge in networking concepts and areas where wireless connectivity solutions (hardware & software) will play an effective and major role in the IoT.

Programming & Artificial Intelligence

Networking or rather communication cannot be established without adding some intelligence to the embedded systems, this intelligence can be added to the devices or the chips with programming. Choosing the right programming language is always a tough decision in IoT; Besides Python, Rust, B#, Parasail, Arduino programming languages – commonly used in building sensor and automation projects, open source environments such as Node.js, is becoming the language of choice for IoT. The early IoT devices are run by rule-driven programs/apps such as IFTTT or Tasker; AI that could pass the Turing Test would be required for complicated decisions.

Machine Learning & Analytics

The key concept behind IoT is to interconnect things, this we would be able to do it by Mesh Networking, which we discussed earlier. Imagine a scenario where a manufacturing unit/machinery in a factory senses which of its parts are faulty, and to which extent the unit or component could work and how it can impact the production; for such scenarios, data sensors play an important role, and Machine Learning helps predict the outcome by reviewing, analysing and identifying the patterns from these devices, keeping mesh networking in the backdrop, these sensors would generate immense amount of data that should be interpreted. That’s where Big Data comes into picture.

Big Data

We are moving towards a world where every bit of information is important, may it be for forensics, may it be for error detection, or even improving a system by predicting its patterns as discussed earlier. Organisations tend to collect data that is relevant while sifting the redundant data, and for this to work – Big Data skills would be required to improve the functionality of the IoT devices. In a way, Machine Learning and Big Data are interlinked and they strive towards streamlining the functionality of the IoT devices.

Information Security

The heart of every technology is Information Security; since IoT devices exchange an immense amount of data, and process the information between multiple devices – Privacy & Security become a major concern. The security of IoT and the vulnerabilities that they contain have been discussed several times at Security Conferences such as BackHat, DefCon, NullCon, etc. Security analysts have been finding vulnerabilities ranging from buffer overflows to command injections, from plaintext and hard-coded password to a vulnerable AP connection. The demand for VAPT and Security Analysis professionals is ever increasing day by day. Moreover, IoT is moving towards a Mesh Network as discussed previously, and one weak link in the chain can compromise the entire grid by opening up doors where there is a peep hole. A minor vulnerability in a thermostat that could leverage the attacker’s privileges, can open the doorway to the home/office’s smoke/fire alarms – when the alarms are activated, they would open the (access control) doors by design, which would pose a serious threat to the data within the organisation or the safety of the residents in an apartment complex. A few months back, Jeff Voas from NIST has released a publication that helps researchers understand IoT and its security challenges. The publication can be found here.

UI/UX Design

While Information Security is the heart of every technology, UI/UX Design (User Interface/User Experience) is how we can perceive or form a first impression of the device(s). A seamless design, that can interconnect multiple devices or options to create a smooth UX, with a minimal learning curve can change the way an end user can perceive ‘Things’. Considering that there would be a plethora of devices in IoT, having a different app or UI does not make sense to the end user who would have to re-learn every time a new device in added to his/her IoT. Adding on to that, IoT devices are cruising towards eye or hand gestures and even voice inputs; for such devices “it is critical to consider the aesthetics of the gestures or voice commands”. So, designers should start venturing into the deeper technological/hardware aspects, towards a world of sensors and holographs; to come up with a great UX. Designers who can encompass all of this, would prove a valuable asset to the field of IoT.

Cloud Computing

The idea of IoT is inter-connectivity, where in the machines are linked to web and constant data flows through it, thereby making it work on a real-time basis. In a world where every “thing” can be assigned with an IP address, cloud computing acts as a huge brain. Earlier, we talked about Big Data and how IoT would generate volumes of data for use. Data storage of this data would have to be considered and managed efficiently; in a way, “cloud computing and IoT are tightly coupled”. When data of this size that is easily captured, it also has to be re-worked upon to make it consistent and valuable to the devices and the entire infrastructure; that is where the ‘huge brain’ comes into picture. The data is transformed to be productive at real-time and assists in making decisions while optimising the inter-connectivity, especially with cloud providing the virtual infrastructure that is scalable – would assist organisations in accessing the applications/data on demand. Knowledge and experience in Cloud Computing Platforms such as AWS (Amazon Web Services), Microsoft Azure, Cisco IoT Cloud Connect, Salesforce IoT Cloud, IBM’s Watson, etc. can help the business grow.

Managing The Cloud

The idea of having almost an empty HDD with just the OS and a couple of other useful applications while we have the data on the cloud, accessible to us at any point of time, ubiquitously, is something that many would go for. Its like having a house on wheels that’d follow us wherever we go, may it be the south pole or the Sahara Desert or even the moon. Fascinating isn’t it?

Cloud Computing gives various opportunities for all kinds of organizations with different ways of obtaining services and provides benefits that includes flexibility, usability, disaster relief as well as cost reduction. The cloud covers a huge array of services and delivery models ranging from in-house virtual servers to software accessed by multiple organizations over the internet. Many enterprises have been moving their organizations to cloud computing and the economy has driven many firms to consider cloud-based services. When companies start considering cloud, most of them just look at the benefits of the cloud and ignore or side line the most important factors before they shift to a cloud based service. And the important factor that companies need to consider is the ‘Risk Management’. Companies need to understand that the infrastructure wouldn’t be there in their hands once they go on to the Cloud. There would be a huge change in the way the entire organization/business runs, an end of an era in a way. The cultural shift should be monitored and the consequences should be well planned and managed. Once a business goes onto the cloud, the entire business runs on the network connectivity. The data transmission increases many fold and there should be more than a person to manage the entire network service and its performance. If the network fails, the accessibility to the data, applications and resources would also vanish. So, its important to have a backup plan. A really good relationship with the connectivity providers would be an added advantage and that would help for the speed of the resolution.

Moving the business to the cloud is not giving up our managerial role, its more like a shared responsibility. The cloud provider also becomes a partner of our success stories. If the risks are well managed the rewards are tremendous.
